Absolutely terrible. Would never fly American again. 2 deplaned incidents and delayed by close to 24 hours. $12 meal voucher for first class passengers was an insult to the injury. Pathetic.

Absolutely terrible. Would never fly American again. 2 deplaned incidents and delayed by close to 24 hours. $12 meal voucher for first class passengers was an insult to the injury. Pathetic.

Terrible planning. And even worse gate agents. Absolutely rude behavior.

Half of the TSA checkpoints at PHL are closed. Also, there is no standby for first class passengers. You can only standby for coach. Very dated policy and inconsistent with peers.

Flight was scheduled at 11:26am but they keep Delaying until midnight. They waited at airport restless.

Rough flight No beverage service due to turbulence Bottom Seat cushion was non existent

Great experience. Good dinner and service. FA's were very nice and attentive.

It was great. Smooth flight, comfortable, left on time and landed on time.

We hoarded. Then we deplaned. Then we waited for 10 hours in the MSP airport due to a wheel misfunction. We understand safety but communication between crew and airport staff was horrible. When we did finally board, we were rushed on and because we were waiting for a “fresh” pilot and crew, we sat in a roasting plane with no A/C for an hour. My question is why was this flight not cancelled right away when they knew this would be a huge issue OR, why did AA not get a substitute plane, considering this was already a full flight? To me, this appears to be a complete breakdown in leadership and utter systems failure. The compensation for completely disrupting travel plans for hundreds, which we paid dearly for, was measly. While we appreciated the lodging for the night, $12 in meal vouchers isn’t going to sustain anyone for over 12 hours. “We apologize; our hands are tied” is no longer an acceptable explanation. We are so completely turned off by this experience and will definitely seek alternative avenues when we need to fly.

Mostly good. The WiFi wasn’t working so that was not great.

I rated the experience "mediocre" because of the 2 hour delay in take off. This is the 4th flight from DFW on AA where there was a delay and in one of the instances (after 13 delays), the flight was cancelled. I understand weather but for the March 18th flight, there was no weather issue in Dallas or Detroit. I called Concierge Key and they were wonderful, booking me on a later flight in case my flight was cancelled. I have flown with American for many years and never has there been this consistent pattern of delays. Very disappointing.
