Pros: The wonderful crews and the comfortable seat
Cons: Snack and drink
Cons: Wouldn't let us on the flight when there was plenty of time to get there. Manager was arrogant and slow - didn't care. Poor policies at that airport.
Pros: Delayed flight no reasons seems like American Airlines don’t know what to do in these situations
Cons: I believe this airlines should have figured the answer to this question by now.
Cons: Sarasota ticketing agent was not very nice at all 😟 Houston Gate agent was not nice either. We were treated like we were stupid for asking questions. I hope it’s not racism issues. I wished I had taken their names.
