Cons: I believe this airlines should have figured the answer to this question by now.
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.
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
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.
