Airline reviews

My flight was delayed twice. The first time because of “plane maintenance” and the second because the previous flight who supposedly “arrived early” took an obnoxiously long time to get off the plane. Total delay was over an hour for no reason. Not to mention your airline repeatedly changed our gate from one end of the terminal to the other. Not very happy about this experience. My previous flights with American haven’t had this many issues.

Total delay was over an hour for no reason. Not to mention your airline repeatedly changed our gate from one end of the terminal to the other. Not very happy about this experience.

Very turbulent flight, no drinks, very little service, unorganized boarding, gate changed multiple times

We’ve had a year of delays with American, and this one was another flight to add to that list. It just reduced our vacation by a day! So frustrating. In-flight entertainment (TVs) weren’t working, There was no drinks service due to delivery issues.

The plane was experiencing problems with the HVAC system, it was very cold in the front of the plane and very hot in the back.

The boarding process needs to be fixed. The zone don't work, especially when there is hardly anyone in zones 3, 4,and 5, leaving the majority of the passengers backed up in the aisle, especially because passengers seated near the front are blocking passengers who are seated in the rear of the plane. It would also help if the size of carry on bags was more strictly enforced.

In flight connectivity (via T-Mobile) was often not working.

Terrible. Internet/kiosk glitch prevented baggage checkin. Line at ticket co in Ter was under serviced and did not move. Agents did not call for flight but rather allowed time to pass. Then told each person as they reached the front if line that it was too late to check bags so they’d have to rebook flights. At least 15 people missed the flight as a result of this incompetence.

It was exactly what I expected, actually arriving sooner than scheduled.

Terrible, they canceled my flight due to an issue they had, couldn't fly me into the same place within 24 hrs so had to fly in 2.5 hrs away from my destination and spend even more money. The customer service was terrible (except at the airport in Charleston). Had to call to get my checked baggage fees reimbursed 2 wks later in which one customer service agent was very rude, wouldn't listen and then hung up on me. The second lady I spoke with was actually able to help me with that part thankfully. Would not recommend flying AA.

Delayed, missed connecting flight, ground crew double charged for international charges, were super rude and told me to just”deal with it” when I complained. Horrible airline, very frustrating.
