Plane congestion resulted in a 1 hr wait from landing to arrival at the gate. This was in addition to also experiencing extreme delays on my incoming flight.

Plane congestion resulted in a 1 hr wait from landing to arrival at the gate. This was in addition to also experiencing extreme delays on my incoming flight.

Delayed too much. 1.5 hrs in the airport and another 1 hr in the runway. Got too late in the night. There was no proper food available.

awesome team work seen since on board till off plane in my destination. thanks you so much.

Job well done, being treated for good and helping a lot . thanks you so much till will meet against.

Very disappointing that on an international business class flight they would not give me access to the lounge in Boston. They said it was because it was a codeshare flight. International business class should include lounge access regardless of codeshare.

They did not have free WIFI and I was not okay with that!

Flight was on time, clean, etc. Despite connecting to your wi fi I was unable to use your app to watch entertainment.

Both my flight where delayed Had 25min to make it to my transfer flight

I just got back from a trip with 3 flights each way. The flights were good and we were happy with out experience. There was one steward on our first flight that was harsh and grump with passengers. It did not leave a good impression. All of the other flight crews were great on the other five flights.

They changed my flight 5 hours before it took off and changed my connecting airport messing up my entire 1st day in Japan.

We had to de-board do to maintenance and there was ZERO help with getting rebooked. The flight was delayed by over 24 hours. Quite ridiculous. When I. called Kayak to get help to rebook, they said they couldn't and that it had to be done at the American counter that didn't exist without going outside TSA security, which I did.

I spent 12 hrs getting home and had a direct flight that should have taken no more than 3 hrs. The first plane has an issue, was on the plane for over an hour before we had to deplane and move from A19 to A39 to board another plane. Boarded that plane to wait for another 45 minutes for it to also have an issue where we had to deboard. After everyone had went to get something to eat the food vouchers came out and half of us could not use. We then had to wait until 8:00 pm to board and finally got to Columbus Ohio at midnight. We were told that our luggage was on baggage 5. I waited 30 minutes to then realize my luggage was on 4. No notification sent. Horrible communication and I have a priority status.

My flight depature was changed. Then it was delayed, and then cancelled after I reached the gate.I paid $231 for a hotel room that I didn't get to use because I arrived 24 hours later than I was suppossed to. My wife had to pick me up from the airport and I had to pay for an another ride back to the airport the next day. They did get me faster/ priority through TSA. The 2nd flight was okay

Both directions of our trip were befuddled by massive delays, one of which led to our connecting flight being grounded mid air due to storms that we’d have missed if we were on time. The other our originating flight was delayed repeatedly until it arrived at our connecting airport later than our final leg was even supposed to have arrived. American cannot seem to manage rebooking s for a family party… both directions we had to come up with a plan to get to Boston stay overnight only one night each direction was covered by the airline -and take a bus to or from our destination. Missed an entire leg of our trip, hotel cancellation fees, expensive stay in Boston and bus ticket expenses are unlikely to be comped and the meal vouchers are worthless.

My flight was 4 hours delayed on departure at 6a causing me to miss my connection at DCA. I had to scramble to find a seat home on a later flight and instead of an exit seat, I was in row 30 on a flight getting me home 5 hours later than planned. The AA team on the ground did a fine job. AA continues to run the airline like the passengers are cargo.

Flight delays for communication overall not a good experience uncomfortable on the plane. Person in front of me reclined his seat, putting them inches from my lap.

the plane was so hot!! the air-conditioning was barely blowing. The flight was delayed, and we had to sit on the hot plane before take off for an extended amount of time, waiting on international passengers. Would not have been so bad if it was not so hot. They said it would get better after take off, but it did not.

The plane was probably full boarding was easy. We were able to check our carry-on luggage for free. It was a return flight through Philly to LA. Never saw a stewardess do a demonstration of emergency Procedures. I think my flight was pretty full

Flight was delayed after boarding and no idea when it would take off. Crew in Portland did arrange for transport to Boston for a different set of flights to my destination.

Seats are so close together. Middle seats should be discounted.
