Ryanair, too. They will fly you to $MAJOR_CITY* for just €0.50†!

* Where we actually mean "a smaller airport 150km away from that city and you're on your own for getting to it"

† Plus €20 ticketing fee, €20 payment-processing fee, €20 boarding-pass issuance fee, €20 checked baggage fee, €20 carry-on baggage fee, €20 fee for no baggage, €20 plane-boarding fee, €20 airport use fee, €20 fee-handling fee and other additional fees as indicated in the terms and conditions

The far away airport is indeed buried in the fine print, but under current law (at least where I live) the advertised price has to be the final price; Ryanair skirt this by having one obscure credit card that they'll accept without a fee and a big fee for any other kind, but unavoidable fees on top of the advertised price are illegal.

You forgot €20 choose a seat - it's €0 if you want a randomly assigned seat but somehow the website mislead me in to clicking it, it took me 20 minutes to get this far in the booking, I'm scared to press the browser back button and I'm so frustrated now I'm blind to the clear and easy method of modifying the my previous selection, if there even is one, because the page changed as soon as I clicked. Maybe the site has a bug, but who wouldn't know it's not like I'm going to call the airline for support on their website. But it's only €20 and this flight is now costing me €400 anyway so it's not even worth my time to sit here for another half hour trying to purchase a ticket- fee.

Don't they put the "no seat preference" option in a drop-down containing a list of city names or something crazy like that?

Yes! In alphabetical order no less :)

That's worthy of a "Dark Pattern" annual award.

I decided I had to see this for myself. It looks like it's actually the travel insurance option, not the seat option, but close enough:

And it wouldn't let me proceed until I chose something; leaving it at the default wasn't allowed. Very tricky.

A combination of legal changes and consumer pressure has changed that a lot. I flew them recently (for the first and last time - but that wasn't related to obfuscated pricing) and there wasn't much in the way of hidden charges. Checked baggage was extra and there was a tiny card processing fee, other than that I paid the advertised price.

And don't forget, if you close the page and come back a little later, the price will have gone up. And magically if you remove your cache and cookies and refresh, the price has dropped! Man I love airlines.

With EasyJet I've always paid the advertised price, give or take a couple of £. As far as I'm aware they don't have any "first-time flyer" discount rates.
