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.

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.

The Phildalphia to Allentown portion was a BUS, not a plane. All was as expected.

Overall flight was as expected. It would have been better with a couple options for snack instead of only one item and if there was a TV or music as option. But overall satisfied.

AA is fabulous. However , Iberia cancelled our Boston - Barcelona flight the morning of the flight - 9/16/24. This was almost a week ago and we have still heard nothing from Iberia/Vueling. Found out from a kayak email that morning that the flight was cancelled. Iberia Customer service reps wouldn’t help us and said to call Vueling. No one answers phone at Vueling. Terrible wild goose chase on DAY OF TRAVEL. AA came to our rescue.

Terrible. I did not like the delay without recourses to help passengers to get to their destinations. AA used to offer coupons for food and overnight accommodation, but not this time. The flight planning was terrible despite of all the current technology available; AA could have informed passengers better that the replacement flight is impossible today, instead of stringing passengers along for 6 hours before cancellation, so that passengers can make earlier alternative arrangements to get home.

It was a bus not a flight. Okay bus ride.

delayed delayed delayed. was supposed to have a 2 hour layover and very nearly missed my connection.
