I didn’t get on plane. Passport being processed by consulate with visa application. Tried to cancel through underpricer after purchasing cacelling for any reason. No dice, they are thieves.

We boarded but then sat there waiting on some missed connection people to get on so we sat for about 15 minutes for that. Then we sat again because the passenger manifest was wrong and they had to figure it out before we could leave. That took about another 20 minutes or so. The crew was working hard to figure it out so it’s not their fault. It ended up being a system glitch where someone was upgraded to first class while another person was also in the same seat and it just created a mess that took a little while to figure out. They literally went to every person on the plane asking their names to see who was sitting in the wrong seat. I also hate the entertainment that must be watched on your phone or tablet. Just give us setback screens. It’s so much better. Almost every Delta flight has this now and it is so nice to have them. The crew did a great job. I have no complaints from them. They were very hard working, even with the mishap and a disgruntled passenger.

Delays took 2hours and thirty minutes making me miss my connecting flight and make me sit in the Chicago airport for 9 hours

Great. Food going from Australia to the US was better than other way around, but still needs improvement in terms of quality and quantity!!!

The fight didn’t happen because I was rerouted to Trinidad as previously explained.

Boarding always seems a bit chaotic. Seat spacing could leave more for leg room.

Overall, it was a good experience. Boarding was good and there was plenty of overhead bin space for everyone’s carryons (even when we boarded toward the end). Only improvement would be to offer trash service more regularly.

David went above and beyond to make our flight the best that it could be

The negative was the wait at the airport coming back. I checked my bags in, an hour before boarding and I get the notification that my flight was delayed. Rather had gotten the notification while I was at the hotel. Then it was delayed 3 x’s. Ugh!

Plane still had screens for watching movies. Good selection too.

They lost my luggage and it didn’t get delivered until the next day.

Uncomfortable seats and flight attendant was rude as she insisted on waking up my husband to ask him if he wanted a drink. When he said that he was sleeping, she replied “without an attitude “. He was seated at 8c

No food/snack served during the flight. Crew wasn’t interested at all. Flew American First but flying low cost with Ryanair is even better

Very friendly and efficient and smooth boarding. We were even way early arriving at my destination. Thank you.

I liked everything. Except that my neck was hurting on the seat. I couldn't sleep.

I flew out of Reagan National. My flight was delayed, delayed, delayed, and then canceled ...THREE TIMES over TWO DAYS. Staff were seemingly not empowered to provide information on why the flights were screwed up. A real nightmare.

Checking in at the counter was very disappointing. The lady had a very bad attitude and smart at me. She had no smile, did not greet me by name, or acknowledge me as a valued customer. Poor reflection of the airline.

First, to be fair, the flight was on time and the trip through the air was relatively smooth. But the flight was full, and they were checking carryons. As this process went on, the crew got increasingly rude and overbearing. During the drink service, a young girl (maybe 9) who had gotten up to use the lavatory got stuck behind the cart. At some point, she started feeling fearful and overwhelmed. Passengers noticed this and asked the crew to let her return to her seat. They refused. Then she started crying, and they still refused to move the cart forward to let her sit. The poor girl was trying to be brave and compose herself. The crew handled the situation terribly and with zero grace or decency. That episode, to me, encapsulates AA’s attitude toward its passengers. Disgraceful. The plane itself was cramped and miserable, as usual. There was zero inflight media or entertainment, other than the lane and borderline inappropriate jokes the steward made during the safety briefing. Then, of course, it took the better part of an hour for the checked bags to show up at the carousel. AA is no better than the el cheapo airlines these days and a far, far cry from its former self.

DO NOT BOOK THROUGH AMERICAN AIRLINES IF YOU HAVE ANY ADDITIONAL NEEDS. Great flight, crew etc. it wasn’t full so had space to stretch out Only downside was there was no GF option for my partner. We booked through American and it was a Qantas flight so despite contacting both airlines to confirm, she didn’t have a gluten free meal for the 16 hour flight (nor the flight in the other direction). The flight attendants did their best to accommodate but it was not super substantial.

I think I paid for an extra legroom seat and to be honest, there was not a lot of space available for my not very long legs. The flight was totally full and the staff did everything possible to meet the needs of all passengers. My only concern was for the size and spacing of my seat.
