I'm usually a United flyer but had booked PHX-BUR on AA for August 11 and they cancelled my flight and moved me to the later flight which gets me in too late to attend an event I have tix for that night. So - I wanted to change to an earlier flight into LAX. Both the app and the website give me a message that I have to call to change this flight which is mind blowing for a such a simple thing. I'm on hold with for at least 20 minutes because when I tried to choose 1 for a call back it keeps telling me it was an invalid choice and then I reached my maximum allowed choices. Then the agent tells me I couldn't change it because it was basic economy - which it wasn't - it was main cabin extra. He's like huh - that's weird and of course changes it. Is this normal or am I just allergic to AA's tech? I would have sorted this whole thing on United in 30 seconds.
