The "search by price and schedule" feature makes it easy to see what options you have on AA if you choose to go that route. Without even clicking anything, you can see the effects of leaving on a different day, choosing a different fare class, or taking a connecting flight versus flying nonstop. This makes it pretty easy to compare. (It is arguable that there are too many options. But this is becuase air travel is expensive by default, and people want cheap. So there are a lot of "discounted" fares around. If you don't want hassle, pick "search by schedule" for the search type, and "economy without restrictions" for the fare type. You will have your ticket in seconds, won't have to pay for checked bags, will have the option of paying $50 to upgrade to first class, and can cancel or change the ticket at any time with no fee. The only downside is that the ticket will cost 10x as much.)
Most people don't know about these sites. AA makes money for every person who is clueless. And there are many.
(This is why I'm not a business person. I know what it takes to run a successful business, and I don't want to do it.)
Any savvy traveler knows, the "budget" in budget airlines refers only to their operations, not the final price you pay once all the fees, transfers etc are tacked on.
Even with premium rate phone numbers, call centres are still expensive.
If this means that someone has to pay $35 because they can't follow the directions on the website, I am not going to shed many tears for them.
Having been a customer of AA before vowing in disgust never to let them take a penny from me ever again, I surmise that the hidden plan here is to make you call their customer-service agents to book or change your ticket, since you can't work out how to do it on the website. At AA, calling them to book means a $35 extra fee on top of your ticket.
So that's it? They have the worst website in the industry just to screw their customers for a lousy $35?
