Reviews
Pros: Everything! From ticketing agent to all the crew on our flight back were awesome. Thank you!
Reviews
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.
Reviews
Pros: The comfort of the plane was great! Lots of room and very comfortable seating.
Cons: I found some members of staff to be a bit rude. When other passengers asked questions or did something wrong (that was a minor issue), one of the staff members in particular talked down to them and treated them like they were stupid.
Reviews
Pros: Well, it was not very comfortable and we were delayed for an hour. And a crew member was sick.
Cons: Mostly everything.

Reviews
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.
Reviews
