This seems like a huge stretch of "dark pattern".

Ultra low-cost airlines are pretty aggressive in upselling seat / baggage / food / fare class upgrades during the checkout process. It is annoying to have no idea what a ticket will really end up costing when it pops up in Google Flights or whatever, but I don't think that's enough to call it a dark pattern since everything is clearly disclosed before you pay for anything. Airlines are very upfront about all the things you aren't getting with your ticket.

I haven't booked a flight in a while but any situation where I don't know the "final" cost of my ticket before I start the checkout process is a dark pattern in my book.

I don't want to see a $100 ticket before I start the checkout process but end up seeing $200 on step 6 / 8 because if I want to sit down and carry a backpack with me it's an extra $100.

That forces me to give them my data (I'm interested in a flight from X to Y, creating accounts, my address, etc.) even if I back out of the checkout process due to upsells.

Compare that to seeing the final cost ahead of time before entering in any billing details and if you don't agree with the price you can use a competitor with better rates. There's no contest in how much better of an experience and outcome that is for customers.

Not knowing if you paid to choose your seat or baggage at the time of checkout is a reading comprehension issue.

There's a valid complaint that they all game what's included/excluded at the listing price so they sort better in the fare compare websites. But once you go through the sales funnel, if you read, its very clear what you are getting.

It's not about reading comprehension or the lack of it.

It's saying the list price is $100 but then you have to invest time and provide information during the checkout process only to find out on a much later step that the list price is no longer the price you were given.

You're being lied to about the list price which makes it harder to compare prices at a glance and companies are preying on you through a form of "the sunk cost fallacy"[0] in that you're more likely to finish checking out because you've invested so much time already to get to step 6 / 8.

This is not what airlines do though. The price on google flights is the exact price I pay to fly because I don't check bags or choose my seat. Just because other people do buy those things doesn't mean they have to or were tricked.

Just because the trick doesn't work on you because you don't do what most people do doesn't make it not a trick.

Right, I think airlines are a bad example of "dark pattern" and "junk fees" because ultimately the customers are the problem.

Every airline that has tried the premium model in recent decades has failed.

People have decided they've reserved the right to rock bottom fares and simultaneous complaints about quality of service. Or people have decided flying sucks no matter what airline they choose so they simply sort by price.

Either way, dollars vote and this is the outcome.

I just tried to find a roundtrip flight from SF to LA on Google Flights. Spent some time comparing prices, different airports, etc. Ended up picking one option, click, click, click - I am on the airline's website. More clicks and I am able to select the seats: went through all available seating - there is nothing available at the price that was originally surfaced to me. I can either upgrade to Delta Comfort+ for +$60 or to First Class.

Sure, I can go back to Google Flights and repeat the process. But I wasted 10 minutes already, and if I had a legitimate need to fly to LA I would have most likely just upgraded to Comfort+ to save time.

Are you going to blame me - the customer - for this?

If it's Google Flights' pricing cache being out of date then that's not an airline dark pattern (Its also possible there is a website dark pattern designed to make an option to pay less by not choosing your seat really non-obvious: I've never booked with Delta)

The airline would say it's your fault for getting a quote from an aggregator rather than direct from them though

It's not. Delta shows me that there is 1 seat available at this price.

Here are the screenshots: https://imgur.com/a/X923fSo

To be fair, you can still purchase the ticket at the advertised price without selecting a specific “preferred” seat. They’ll give you a seat assignment at checkin or at the gate (usually one of those “preferred” ones).

That said, the fact that this situation is unsurprising to me is itself probably evidence of the communication problem. Google could do a clearer job of qualifying the “free seat selection” they falsely promise for that fare, and Delta could do a much better job of saying “there are only paid seats left, but if you don’t want to buy one, you’ll still get one at the airport.” I feel like JetBlue used to do a good job with that.

I think in his case it's actually a legit website bug/issue. If you try to click through without choosing a seat it doesn't actually work on this particular sales funnel and pops up an error. My suspicion its something to do with it being a very close in flight (2 hours to takeoff). So you have selected a fare with seat selection included, but there are no seats actually left .. maybe some cache isn't updating at minute level frequency.

You don't have to select a seat. Your screenshots (specifically the last one) indicate the product you want to buy is available at the price you want.

What product do you think I am buying? A promise that they might find a seat for me if I show up at the airport?

It puzzles me how many people at HN are so eager to defend dark patterns.

If you look at the screenshots with more attention:

1. Google tells me that the free seat selection is included

2. Delta tells me that if I agree to this price, I will be able to reserve the last available seat on the flight (for this price)

3. Once I confirm the price, Delta tells me that I can’t select the seat, it’s not available. I can still buy the ticket, but the offer has changed. Sure, since clearly I need to get on this flight (booking it last minute) - I would rather pay a bit more to make sure I do have a seat.

This is what dark patterns are all about. How is that so hard to understand?

Because this isn't a dark pattern??? The alternative is you not being able to buy this product, which is much worse!

This fare comes with preselection over a limited set of seats. There are no more seats available for preselection in that set. If seats were available you would have been allowed to select them; otherwise, you will be assigned one at the gate.

It is very unlikely that you will be involuntarily denied boarding, and you can be denied boarding in the event of an oversale even if you have an assigned seat.

Note: your fare never indicates that you are buying a particular seat. Please read your contract of carriage closely. Maybe this part (not the offering of the ticket you're complaining about!) is a "dark pattern" (nobody reads the contract of carriage) but it's just literally how airline tickets have always worked.

Wow, ok. You think there is nothing wrong with the airline telling me that 1 seat is available on one screen and then telling me that there are no seats available unless I pay more on the next screen? (If I go back to the previous screen it still tells me that 1 seat is available.)

The alternative to this is that when I compare prices of different flights I see the correct full offer for the price I want to pay. This flight is not the only available flight. I would have chosen a different flight on Google Flights if I had known that there are no seats available at this price. But now I am 10 minutes into the process and just want to be done.

What is a dark pattern by your definition? A literal picture of a pattern colored dark gray?

> airline telling me that 1 seat is available on one screen and then telling me that there are no seats available unless I pay more on the next screen?

This is a misunderstanding. Airline does not tell that you need to pay more. You can click on Continue button and complete the purchase. Even the popup you have shared tells you exactly this.

Yes, you are right. When you reserve a "table" at a restaurant you are actually not promised chairs. If you want to reserve chairs - that’s +$20. Don’t want to reserve chairs? Just show up at the restaurant and there might be chairs available.

This is a great example. When you reserve a table at the restaurant they might offer you several seating options when they are not busy. But if they are full they will get you seated and not ask you for extra money. But you may end up next to the toilet.

Try reserving a specific table at the restaurant. An hour before the dinner.

That's not the point though. The point is that when you place a reservation, certain things are included. In the case of a restaurant, chairs are included. In the case of Delta, they explicitly state right under the agreed upon price that there is a seat available that I can reserve. It might be close to the restroom, sure. But they should not list this offer as inclusive of seat selection if there are no seats to select.

For some reason you fail to acknowledge that features listed under the price must be included in the price.

> Try reserving a specific table at the restaurant. An hour before the dinner.

Restaurants don't allow you to go through the reservation process to only suddenly mention at the last stage that the table has no chairs, or no table top (just table legs).

> Restaurants don't allow you to go through the reservation process to only suddenly mention at the last stage that the table has no chairs, or no table top (just table legs).

Are you under the impression that they are going to make you stand up on the flight?

There is no ambiguity there. You will get an economy seat or better. If non-premium seats available you will have an option to select one for free. If not, they will assign a premium economy or a comfort+ seat at the time of check-in. If the flight is overbooked having a preselected seat does not guarantee you won't be bumped.

This is something I've observed with different airlines. Google's line "Free seat selection" doesn't guarantee availability of seats to choose from, just that you won't be charged for selecting one if available for your fare.

Delta tells me that there is a seat available at this price before I agree to it. After I agree to it it tells me that there is no seat available at this price unless I pay more.

The agreed upon "seat" in this context includes the selection. This is what this specific dark pattern is about. They are misrepresenting the value of their offering. I want to be able to reserve a seat on my flight. Not to reserve a promise that they will assign a seat... if available, obviously. If not I can just book the next flight and wait for a couple of hours at the ariport. Perfect.

A low to negative economic Google product that is poorly supported, hard to imagine, right?

Maybe Google Flights is the issue here? I always use Kayak.

It shows you with little logos below the price if it includes seat selection, carry on and checked baggage.

For a frequent NYC-MIA flight I take I ran a test.

When I clicked through the first random AA price, and then the first random Delta price option I saw, it took me directly to each airline checkout at the exact price listed.

Can you give me the exact dates and flight times so I can validate this?

Here is the specific Google Flight I selected: https://www.google.com/travel/flights/s/yYPhNC6aXX4VP5cj8

Here are the screenshots: https://imgur.com/a/X923fSo

That's an issue, and going from kayak to delta for same flight leads to same issue.

I wonder if this is some bug/edge case for really close in flights? The example flight booking takes off 2 hours from now?

Last time I ever tried to book a flight so close the online sales funnel was closed due to post-9/11 security restrictions. I think 2 hours is about as close as is even legal right?

Can you replicate for a flight tomorrow / next week / next month?

In my experience this replicates routinely for Delta Main Cabin fares for non-elites on leisure/non-corporate travel once only “Preferred Seats” are left in the economy cabin.

What I think the other carriers do well is detect when there aren’t non-charged seats available for advance selection, and remind you that you can continue without paying for a specific seat and still be guaranteed a seat on day of departure.

Delta hand out “free preferred seating” as a perk to all sorts of categories of traveler though. I wonder if that complicates the prospect of offering that kind of warning.

Urgency is one of the key motivators for using dark patterns. Wouldn't be surprised if Delta defaults to "1 seat available at this price" for all busy flights within X take off time regardless of the availability.

I see, thanks.

On an entirely different note, this feels like an exclusively Delta fuck up (and they know, given that they built a whole pop up for it). I fly United and American extremely frequently and never seen this. I have even booked Alaska basic economy that doesn't give you a seat and been given a free seat selection. Delta has been rapidly going downhill in recent years -- those that nerd out on air travel know exactly what I'm talking about.

I expect these patters from all low-cost airlines, so fly Alaska whenever possible.

I used to fly between Portland and SF often and Alaska was the only airline that never screwed me.

The dark pattern here is that you don't actually have to choose a seat. You can click they disabled-button-colored continue button, click through the warning about not choosing a seat, and avoid paying for the seat choice cost (on each leg there and back).

As a solo traveller, you may not care. As a family you really don't want to be seated away from your kids. If you don't pick seats, will you get seated together? Who knows. Depends on if enough other people who want to pay to pick seats leave enough seats together for you... on a popular flight, that's doubtful.

So it's not just people choosing to pay for a luxury, it's a tax on people who don't know they can skip the step, and on families who may know, but can't roll the dice.

>People have decided they've reserved the right to rock bottom fares and simultaneous complaints about quality of service.

That's not really the case. Airline prices are quite detached from the quality of service. They are more a function of what the airline can get away with in the moment (i.e., surge pricing based on demand). If airline prices were always $100 for low cost, and $200 for frills included, that would be a fine trade. But you will pay anywhere from 100-1000 based on demand irrespective of frills or no frills.

It depends on what you call “premium”.

Delta and AA are still the largest airlines in the US and unless you buy the basic economy tickets, the experience is a lot better and you aren’t nickel and dimed.

The Delta CEO said that only 5% of customers buy the lowest tier ticket.

You might be looking for a different word here. A dark pattern is not fraud or outright lying. These are already illegal. Seeing the total price at the end of the purchasing process is the legal requirement for a sale.

A classic example of a dark pattern is AirBnB. They (used to) show listing prices without all additional fees like cleaning, service fees, etc. So users would end up wasting a lot of time on finding the right offering to only later (yes, before checkout) realize that the total price is actually much higher. Users know how much they end up paying, it's not fraud. But this is still a dark pattern.

Well, I'd argue that you're looking for a different term, but obviously there's no concrete definition here.

I don't think a dark pattern requires any fraud or lying. I think the most obvious example is having users opt in to something (e.g. sharing private data) by default and only offering the option to opt out by navigating some convoluted series of menus. You aren't explicitly lying to users and telling them they can't opt out, but you're going out of your way to make sure the option isn't advertised or easily accessible.

In my opinion, there's a gap between that and what airlines and AirBnB do. I guess there's an element of deception with both, but airlines and AirBnB are just waving a nice number in front of your face to drive engagement. That doesn't personally meet my threshold, but I understand how it might meet yours.

For all that Booking.com has lots of annoying patterns like telling you how many people looked at a listing and that there's only two rooms (currently) available for those dates, I do like the fact the price I first see in the ranking is what I pay. Not least because the AirBNB fees usually seems to be how much more it costs to book with them if they have a listing for the same place.

>Booking.com has lots of annoying patterns like telling you how many people looked at a listing and that there's only two rooms (currently) available for those dates

Assuming they're not making up the data, why is this bad? If a hotel is very popular and almost sold-out, isn't that something useful to know when you're making reservations? Sure, it does feel a little high-pressure, but if it's truthful (normal "high pressure sales" tactics aren't, they create a false sense of urgency when in fact there's no shortage at all), it can be useful if you're trying to book a room at a popular place or during a peak time.

In practice I think it's usually inaccurate for medium sized hotels not because Booking.com makes up the data, but because the hotel doesn't release all its inventory to Booking.com at once. Otherwise it's not bad per se, but in combination with the "two people looked at this listing recently" in similarly red letters and all the book now pay later stuff, it does feel a bit like booking with someone shouting at you to hurry up

For what its worth, I often fly from one location to another without luggage (going home to visit parents for instance). its actually my far my most common mode of flight since I visit them 3-4 times a year.

I appreciate the fact that I don't have to subsidize other people who need luggage.

For my last flights, all the fees WERE disclosed well in advance. These airlines WANTED to sell these options and were marketing them diligently to the point where you had to fight these unbundled options with a stick.

There may be some bad guys but the unbundling seems to result - at least for some airlines - in excellent disclosure. Granted now you have to read through a lot more, and you have to select or ignore all these offers. Including pick specific seats if you do want a lot more space.

If anything, I wanted to pay for some more options that were not offered.

Yep, I'm hella tall, I want to know up front I can pay to reserve a seat with more legroom.

And speaking Spirit, Big Front Seat is probably the best value in US domestic aviation. You get a business class seat for a fraction of what the legacies charge.

ironically airfares are one of the most transparently priced services in the whole country because Obama passed a law that forced them to show the final price with fees and taxes included in the list price when searching

pretty much no other good or service in the US can say the same

Gasoline?

"Pretty much" implying there are exceptions, yes, but it's not the norm in the US for list prices to be inclusive of all fees and taxes.

The hidden motivation there is that the government's rule benefits the government. It's easier for them to raise their taxes and fees, by hiding their portion in the total price where they won't get blamed. (You can find the breakdown if you look for it, but who ever bothers.)

They're transparent in the sense that they tell you the cost and it's the same when you checkout 5 minutes later.

But calling it "transparently priced" is nonsense. Fares change based on multiple variables. The fact that getting the lowest fare means navigating the permutations of date of travel, date of purchase and location of purchase to find the lowest combination of the three can be maddening. I shouldn't need a VPN and a comprehensive understanding of airline pricing quirks to not get overcharged, often by significant amounts. And it shouldn't be possible to get a lower price by using airline points as an intermediate currency, especially since the aggregators do not list the cost for flights in points.

not sure what you think should happen. there’s a limited number of seats per flight. if there’s 10 available seats left and 8 suddenly booked why should the last ones be priced the same

Some the variables should be illegal, though. A seat should cost the same whether I'm buying it from my computer in California or Lima, Peru. And the kind of travel hacking that allows someone to purchase 100k points to buy a seat using points for less than it would cost to purchase the same seat with cash should also be regulated away.

A 2-dimensional search is much easier to navigate than a 4-dimensional search. Aggregators have searches based on flexible dates. And they could combine them with Camelizer-style watching of fares to alert people when they get cheaper as well as providing historical averages. But as soon as you start throwing in more variables, it stops being possible to make sense of it all.

But also:

> if there’s 10 available seats left and 8 suddenly booked why should the last ones be priced the same

You could say the same about any product. What if a grocery store applied the same policy when it came to milk? What if Apple charged more for iPhones when a store was running low? What if a gas station charged more based on the level of their storage tanks? You don't think there'd be outrage if we started to see these airline pricing practices seep into the larger market?

Is there outrage when a clothes store puts the items they haven't been able to shift onto the sales rack? Is there outrage when a grocery store puts discount stickers on the food that's approaching its sell by date? Dynamic pricing is a fact of life in very many sectors.

Because raising prices just because you don't have many left is price gouging. Turns out people don't like being charged more money for no reason than "fuck you, that's why".

I feel like this is different than a hotel 'resort fee', which you have no way to decline.

I hate flying Spirit but I have flown places before where I only needed a backpack. It may only be 5% of flyers on any route, but there are a lot of airlines to it makes sense that an airline with the model "if you are the rare traveller who doesn't need luggage - we can give you a good price" should exist.

I think it's probably a fair bit more.

It's not unusual for me or my colleagues to do short business trips within Europe with only hand luggage. The cost isn't really relevant, it's mostly the convenience of walking straight off the plane to the train or taxi.

Couples can also have one checked bag between two people.

In the case of Spirit and Frontier, this is literally what they're known for. I'd be shocked to meet someone shocked by that.

The fact of the matter is more legroom is expensive because it means less seats can be in the cabin. Seat selection is expensive as it limits the combinations of available seats for those who want to sit together.

If these things don't matter (I'm a short guy sans family who often does short trips w/ minimal luggage needs), it's great to not have to pay for that.

And the point is that we should not have to live in a adversarial world like this.

It’s not that people don’t know about it

it’s not that people are surprised by it

The point is that we all think it’s bad and that it should change and so we’re pointing it out

I agree that everything shouldn't be as adversarial, but as somebody who's motto for less important/short flights has become "Just throw me in the trash," flying Spirit is fine by me. There's a segment with additional time/flexibility that they appeal to. My concern is when companies go too far in misrepresenting things, especially things that are actually mandatory, and I'm careful because I've come to expect that from most.

Edit: One big issue when flying for me the risk of cancellation and not being reimbursed, but I balance that against the ticket cost. Again, I often have some flexibility around staying in a location longer when necessary, which helps inform the carrier I select.

You want to travel somewhere and pay as little as possible. The airlines want to take you there for as much as possible. It's inherently adversarial.

It used to be the case that everyone bought a bundle that included a bunch of free (not charged at point of use) services. Whether or not you took 3 bags, you paid the same price as someone who did. Whether or not you chose seats all together at time of ticketing, you paid the same as someone who did. With the advent of unbundling (in part driven by online search), consumers could now decide whether taking 3 bags was worth whatever $X the airline proposed to charge. For people who did choose that, they paid more than people who didn't use that service.

https://link.springer.com/article/10.1057/s41272-022-00388-5 has some more information about the evolution of unbundling.

For me personally, I prefer the unbundled approach; it fits my sense of connecting my costs to my consumption (and probably saves me money in total).

> The point is that we all think it’s bad and that it should change and so we’re pointing it out

No, you think it's bad. I may despise Spirit and Frontier and refuse to fly them, but I also think it's a great thing they exist.

I despise them because the lack of comfort/nickle-and-diming is not worth my time, and I can easily afford to pay more for a better experience. But if I were back being 20 years old and broke, and my body could deal much better with being uncomfortable for a couple hours, I'd love the option to be able to fly on the cheap.

Like the other comment said. There's also a time element. Who wants to take four flights, get stuck in an airport, and possible lost luggage when Spirit has a direct flight.

Precisely. You won’t catch me dead on a Spirit/Frontier flight because I can afford more comfortable/reliable options for the length of flight, but I am not the target demographic. Having cheap options is good in any industry. I fly budget airlines in Europe quite a bit because the $ saved per ounce of discomfort ratio is far higher and am thankful they exist. One’s inability to read the conditions of their fare is not a valid reason to eliminate the option for everyone else.

Since when is it “adversarial” to charge people who consume more of the product (more legroom, extra bags) more money than people who consume less? That’s how all businesses work. Is it adversarial for a restaurant to charge extra if you order a second entree?

Not even close to "all" of us think it's bad. I'm happy to fly spirit on short flights since I don't check bags or upgrade my seat. If the budget airlines didn't exist travelling would be much more expensive for me.

They still should be way cheaper if you don’t care about the seats and/or only have hand luggage

I wish they would enforce the "hand luggage" size a bit on entry to the plane, last time I flew around 2017 it was a complete shit show in regards to the overhead storage compartments.

They do, or at least when I last flew they were charging people who had carryon bags that would not go beneath the seat.

(I had a backpack that was slightly oversized, but they did not seem to care that much.)

I guess it depends on how full a flight is. A empty one they don't really care - a full one they care more. But also if its a cheap or "premium" airline.

The budget airlines are pretty strict on this, but the regulars not so much.

Yeah the problem for the consumer is how opaque it is. They're all competing to get the lowest ticket price on the aggregator price, and then claw back a profit either through obtuse language during the checkout process (i.e. insurance which is not clear at all about what it covers) or through unexpected "extra fees" you end up paying between when you get to the airport and when you arrive at your destination.

Ryan Air was so bad with the latter that I flat out stopped flying with them. It happened a couple times I had to pay some extra 40 EUR for not reading the fine print carefully enough (i.e. I paid for a cabin bag, but I had to pick up a tag for it at the check-in counter instead of going straight to the gate to avoid an extra fee)

Imo unbundling is fine if you are allowed to make informed decisions about what you want or not. If you feel like you've been tricked or robbed after using a product it's probably going a bad way.

Was but no longer.

Indeed if you search enough on flyertalk you could find old posts of mine claiming I wouldn't fly Ryanair if I were paid to do so.

But that was before 2018 November when they have changed. I find them one of the best price/fee wise, it's completely clear as what you pay for and what you get. There's no opaque "personal item", no, it's a 40 x 25 x 20 cm bag and the sizer is 42 x 30 x 20cm ensuring anything compliant will really fit. I have yet to find another airline which would so readily disclose the actual sizer dimensions. You want to bring a bigger bag, pay for priority. They only sell a given amount of priority so the bags actually fit on board. You want leg space, here, book an emergency row, yes it has a price but again: you get what you pay for.

Of course, you still need to walk to the plane most likely (sometimes you get on a bus) and then walk up the stairs -- not as easy as a legacy airline with jetways for sure. But then again, no legacy airline, not even all legacy airlines together can match the network of Ryanair, it's really something else.

Maybe but they already lost my business for life. You only get so many chances and there are plenty of other airlines.

> and there are plenty of other airlines

I respectfully disagree: I find myself booking Ryanair more and more because, as I mentioned above, they are the ones who fly on the route I want to fly. Real world examples: I now live in Malta, I want to visit my parents at Budapest. Only FR flies MLA-BUD direct. I want to continue on to my brother in the UK who in Suffolk so out of the many London airports, Stansted is closest. Guess who flies BUD-STN? And they have STN-MLA too. That's three routes I fly often and there's really no competition. It's good they cleaned up their act before I moved back to Europe, really.

Yeah I mean I am only speaking for myself. I am done with them but you are free to fly with whoever you want.

Happened with my boss, a tall guy. He has stopped flying "low cost" airlines and putting up with their BS dark patterns because Lufthansa and other traditional airlines have lower prices once you add lugage and leg room anyway.

Ryan Air are borderline decent if you only carry a cabin bag and get the "prority" package. You should see Wizz Air. They're worse than booking.com and Sixt combined, no flying over Ukraine and getting downed by trigger happy separatists.

Luckily neither one of those companies had any crashes so far, just one Belorussian jorurnalist kidnapped, an engine failure and bird strikes. No crazy copilot killing himself along with all the passengers in the airplane or getting downed by trigger happy separatists while flying over Ukraine.

To be fair I highly doubt any airline confronted by Belarusian fighter jets would’ve responded differently. A jetliner is not outrunning or outgunning that.

I hear you, but I fly spirit all the time with no add-ons at all. No bags, no seat selection, no wifi, no snacks. I really appreciate the low price and select Spirit over my preferred airline Southwest often for this use case.

It's not a dark pattern in my case, even if I do get annoyed those times when I actually have to fly them with bags.

Or companies like Easyjet that save a couple of inches of the dimensions of (previously fairly standard) carry on luggage, so that when you get to the gate you have to fork out £40 or so to carry it on.

Non standardised cabin bag sizes are a nightmare!

It's a lot like SEO optimization and the chicanery that goes on there: Airlines know that customers (a) are using ticket comparison sites like Kayak and Google Flights, (b) customers sort by price, from lowest to highest, and (c) as with Internet search results, customers tend to click on links on the first page w/o scrolling.

"Unbundling" options permits non-ultra-budget airlines to move toward the top of that list, and then make the money back by offering extras during the checkout.

Now, if sites like Google Flights and Kayak would give customers the ability to tick checkboxes saying, "I want a ticket with these unbundled extras," and sort according to the final price, that could potentially re-arrange the field, but who knows? The airlines would probably find another dodge around it.

Google Flights will allow you to select how many carry-ons and checked bags you have (depending on the route).

e.g., on an imaginary trip to Las Vegas, the cheapest carrier changed when I added a checked and carry on bag (and the price difference from a budget carrier to a mainline carrier shrunk considerably).

Sure, but I've not seen them offer tick boxes for things like the ability to choose which seat you're in, or complimentary snacks and drinks.

ZipAir doesn't even provide free cups of water during its flights. They require all baggage, even carry-on, to be under a certain weight or pay an additional charge.

Unbundled options is no longer merely about how many bags you check or carry on. They're monetizing _everything_.

Maybe it's because I use Google Flights, but all of that information is front and center. I've never had to dig for it.

Google Flights does not show checked baggage or non-standard seat fees AFAIK

It only indirectly shows baggage fees with certain airlines once you select a specific flight when it offers you a range of ticket options (e.g. with BA, it shows Economy Basic / Economy Plus options).

Never seen seat fees on Google Flights

I'm not sure what a non-standard seat fee is (it does show prices for seat tiers, such as economy vs first class), but it does show baggage fees for me.

Eg extra leg room seats is what I mean. Ie what the person you replied to meant, what you understood when you said all that information is front and centre…

And what did you mean by baggage? Carry on or checked? I’ve never seen it show checked baggage fees. Maybe just estimates in small grey text somewhere at most

I don't think Spirit makes any secret of the fact that carry on bags are not included in the price? And in any case, the flight aggregators I have used lately (namely, Google Flights and Kayak) make it obvious.
