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: 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
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: Everything! From ticketing agent to all the crew on our flight back were awesome. Thank you!
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
Pros: Quick boarding. Inexpensive ticket. Direct flight.
Cons: Crew walked thru cabin at least 5 times collecting garbage, but could not hand out sealed snack or sealed water. People sat should-to-shoulder - No buffer space, but asked to leave the plane with 6 foot intervals???? This airline picks and chooses their Covid precautions. Quick and inexpensive flight, if you don’t mind the rest.
Reviews
Cons: Boarding at a tourist location is tough but cabin space is prestigious nowadays. Passengers need to be given clear guidance for carry-on baggage since it delays the onboarding process.
Reviews
Cons: The boarding process was horrible. The flight was running late there was no communication until people started screaming at the person behind the counter tell us what the heck is going on. Then they made us walk at least a mile to the plane.
