Even though the seats go back just a little, it is very annoying, and not worth the effort. Fix the seats so we don't have this issue.

I liked watching TV on the AA app. I didn’t like that the flight attendant assumed MY bag was the one that overcrowded the overhead bin and took it up front. I understand a crying baby but when it’s excessive, maybe the flight attendant can offer some assistance to the family to calm the baby down or help them in general and remind the family that there are other passengers on board
