Airline reviews

Boston sucks. Everything after 4p is delayed. AA switched planes on us so we ended up being 1.5 hours late (plus the delay at Logan). Not sure why the airline says it is on time until 1 h before the flight and then it becomes a rolling delay when they knew the incoming flight was arriving after our scheduled departure time. The crew was great as were the gate agent and ground crew. Just operations that sucked.

Flight was 2 hr late but at least I was upgraded to first class

I've flown American several times this summer and I have yet to get a flight that leaves on time. However, a delay is better than a cancel. So far I have had four canceled flights and two delayed flights

The flight was delayed in 30 minute increments for a total of 4 hours and 30 minute delay. All other flights to Chicago left on time except for this one flight. If there is an issue with the inbound flight, just let customers know so they can find another flight right away, Once we got on the plane there was another 30 minute delay taking off at 10:30 at night which is very unusual that a flight wouldn't be ready to take off

They have overselled the ticket and kicked me out from boarding, All my Plans were collapsed and important network meeting missed.also I booked direct flight i have to go through an 1 stop and it was frustrated.

Horrific. We were delayed due a flight attendant stuck in traffic en route to the airport. Over 100 people were then stuck in Charolette. Then I ran to make my layover only to find that my connection didn’t have a plane anymore. Waited 2.5 hours without any updates. On the flight we had to beg for even a pretzel option.

Because I bought my ticket from Underpricer, I could not check in online. I could only check in at the airport and that was deeply frustrating because I had to arrive very early. The flight also departed 45 min late and passengers were given no explanations about why we were delayed. I was worried I would miss my connecting flight. Once on board, however, the flight was fine.

Terrible boarding and first class experience. Nice staff but overall disorganized, dirty plane.

The flight was delayed significantly and we sat on runway after landing for awhile. Best thing was the flight attendant, Jenny, in first class, who was very professional and attentive. She was excellent - the rest of the flight was not.

Early departure meant on time arrival. Only real problem was free internet had issues, although chatting with the internet help desk (you can do this via aainflight.com) got the issue resolved.
