The flight crew was rude. We were in first class and no one even offered water until an hour after we were in the air. Horrible experience

The flight crew was rude. We were in first class and no one even offered water until an hour after we were in the air. Horrible experience

Premium economy seat was decent. As always poor headphones, poor food and beverage, crew is not overly friendly

Great. Quick and quiet and east. The breakfast choices were a welcome surprise!

The stewardess hit me with the food kart twice on the head and didn't say I'm sorry once. The same stewardess gave me a warm Apple Juice with No ice. The Flight was delayed for Departure 6 times, starting from 2:36pm, finally taking off 7:50pm. I was late picking up my child from the sitter by 3 hours.

Did not get the seat I selected and paid for.

My flight was delayed for several hours. Sitting at gate 16 for several hours, I got a text from Kayak the gate changed to 9 before it was announced. Very bad communication at each gate from American Airlines employees. I received 10 notifications of delay from Kayak. My vacation started off horrible! I will write to American Airlines corporate office also.

Delayed flight that lead to a missed connection and a 5-hour trip became a 12-hour flight 🙄

There is no room, no gluten free options, or any free internet/entertainment. You have to bring your own tablet or smartphone because there are no screens.

American Airlines is a mediocre airlines: they do not maintain the highest standard of cleanliness in the cabins, and the food is not well thought out. Service is not at top of mind compared to other international airlines such as Singapore Airlines, JAL or others.

Amazing food, great staff, with one noticable detail missing ...but no seat entertainment in any of aircraft ...I am not a fan

It was perfect. The service was exceptional. I would never want to cross the Atlantic in anyone else's sardine tins.

As I have said it sucked, the ticket counter to have to find and pay for another airline to get home. Now I understand this happened over the weekend but they should have someone there to talk to us instead of throwing the regular crew under the bus.

Everything excellent except for bag drop off. We started at the D area and that was so slow that it was eventually closed just as we were about to go to a station. We then went to F. We got one suitcase checked and then the screen showed that the station was no longer operable. There were long lines everywhere so we had to ask if we could butt in to the next station to finish. Again, this was the only incident, otherwise it was an excellent flying experience

Adequate to good experience. Comfort was mediocre but everything else was good..

Poor all around experience. Sat at gate in Grand Rapids to Chicago for 2.5 hours. No food or water offered and no allowances to use restroom. Missed connecting flight to London and not offered any compensation including food or lodging. Not happy with AA, claims delay was weather related but no weather issues seen on radar. Take ownership for real reason behind delay which was actually the IT outage. Very disappointing and will not be recommending AA for domestic or international flights if this is the way that customers are treated.

Flight cancelled, lost luggage, crappy meal voucher. Nothing was good. Still dont have my luggage.

what would have been better would have been that my booking not been canceled by the system and had I been informed that the booking had been cancelled by the system I could have immediately rebooked and not found out that there was an issue when I was told by the system that I needed to book in. It would have also been good if either the booking agent or BA or anyone been in anyway useful. In the end I had to rebook a flight at an additional cost of $350. So no I'm not impressed by BA any of the other parties involved.

Boarding was poor. Why are first class passengers not boarded first?! Bus to the plane and then held on a packed bus because we were waiting for people on the bus before to finish boarding. Seat belt on the fist clas seat is very uncomfortable, cutting into your neck. Other than that crew, seating and food were all excellent. Entertainment, as usual - rubbish.

I paid for full WIFI- it was terrible, kept being in and out could not listen to a podcast

Flight was delayed but my previous flight was as well so It worked to my advantage. This was my first time in first class. I don't think they ever stopped feeding us. The seating area was very spacious and comfortable. The attendants were wonderful, warm, friendly and very personable.
