Can stay logged in, I mean Venmo stays logged in, but not AA. Someone might steal my phone and book a flight to Boise in a few days in my name. It lags for no apparent reason. Not very good for searching flights and playing around with the dates. You cant set a home city. I guess I have high expectations for a major airline worth 10 billion dollars. I would advise to pass for a better app but ya kind of need it when you fly American.
