Weird broad ad hominem you've deployed to dismiss trying to find better prices
If you actually believe that they are violating the law by obfuscating prices you should contact the DOJ or your states attorney general.
They’re not saying they can’t do it. They’re explaining they don’t want to do it. I have a CS degree and I also hate booking flights. It’s a mess of dark patterns, up-sell, time limits, and details intended to trip up customers. For example, you might not realise there’s an unusually small carry-on limitation until you’re so far into the process that you think “fuck it I guess I’ll have to pay that extra charge.” God help you if you want to compare the exact arrangement between airlines because they do their best to differentiate the service so you can’t compare apples with apples. That’s an intentional product design choice.
I’ve no doubt your mother can book flights. I doubt she’s consistently booking the best value flights.
Really, the problem is that a lot of people that are all-in on AIs aren't very good at a lot of life's little details so they think that AIs will solve everything and don't understand why nobody else agrees. If they got out and lived a little they would quickly realize that AIs are overkill or just the wrong tool for most things, but they have to actually experience life to learn that.
