Hell yeah. The desktop “app” is okay, but I long ago gave up trying to use the app on a phone or tablet, because it just does not work at all for me.
Oh, we have our own terrible airline apps. The last one I used (Southwest, IIRC, but it might have been American) did not even have a list of upcoming flights–which is the single most important thing that the app can do. I want to open the app, click on the flight, and have it give me info like the latest gate, departure time, etc. Nope. I had to put in my name and confirmation code each time to bring it up. And it still didn’t have a single page for all relevant information.
