Frustrating

Downloaded this App to book a flight.
Just that the link to book a flight takes you nowhere.
So I thought, "maybe I need to register first." Which I then did. Or rather, tried. Because the app does not allow to enter a country code for the phone number and also not the country itself. But at the same time will not enroll you without this information.

What is this, a bad joke?

If this is the quality I can expect wit AA, I guess I need to book a flight with another airline.
