Not a bad flight but a long delay boarding and taking off due to the pilot not arriving on time.

I would have preferred a flight voucher and to hop on a different flight. Delayed over 6 hours.

Awful. Delayed flights, missed connection to Toronto. Hotel vouchers were for already booked hotels x3. Giant waste of my time

Boarded early, left early, arrived 40 mins early! A win win for me!

Great flight. Got to watch a movie. Smooth flight and early arrival at ORD.

Overall it was good. I missed my connection but I was put on another flight.

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

The delays (5 hrs) were a comedy of errors, and the multiple safety issues encountered were very concerning.

I don't understand why they can't have charging ports on seats in 2023. They only offer it as a 'premium seat' service. It's ridiculous

Nothing, I wont be flying American Airlines again and will not be recommending anyone to fly American Airlines. It was the worst experience flying I've ever had.

Delayed flight more than I hour. When boarding we spent some additional time on the plane before takeoff ....

They lost my baggage and I am still struggling to the information and update

It was good, the staff was great, and the food, was as usual, tea and biscuit. Bathroom was clean, and the plane was clean as well.

As a first class customer, there was no power the entire flight which limited my ability to work. I find this unacceptable. The first 11 rows on the left side of the plan were out. I was only offered the option to charge my phone which was not the issue because my laptop was out of power. I asked if there was anything that can be done for me, and the answer was, "no". I was not offered any type of compensation for this AA problem which caused me unnecessary stress due to inability to address business issues on an already challenging travel day. Flight attendants tried to reset the power once but that was the extent of their support. Very disappointing for the lack of expected services on a flight. Please contact me with customer focused response to this complaint.

Update to handle the delay was very bad, crews no smiles or welcome or thanks. Don’t care attitude

After we landed we sat on the tarmac for 1.5 hours waiting to get to our gate. Ridiculous.

3hour delay In the last 3 months i had 3 flights and 2 of these had a more than 2:40 hrs delayed

We received a flight delay notification over 24 hours before the flight, but it seems American didn't do anything in that timeframe to get the flight back on schedule. Gate agents were still determining when our plane would arrive. Didn't have catering ready to go when our plane did arrive. Flight attendant timeout before we left. There was a flight attendant on board who could work the flight (trained on that aricraft type and was within hours), however American chose to wait for a backup to arrive, which delay the flight further.

When you pay for Premium Economy on an 787 and you’re promised amenities for the extra money, you expect them to work. They didn’t. USB connector wouldn’t charge continuously. 120v outlet wouldn’t hold anything you plugged into it. The adapter would just fall out. The noise canceling headphones stopped noise cancelling in the first 15 minutes for EVERYONE. No one on the plane knew how to fix it so I couldn’t listen to any movies. I just put in my AirPods and went to sleep. Very unhappy with the crappy Panasonic entertainment system. I won’t buy premium again.
