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

Boarding gate in Honolulu was staffed with a great clerk with a soothing voice despite the flight delay of over an hour. Flight attendants in the plane were all grumpy, not pleasant looking bunch. Their sour attitude showed throughout the flight. Inly able to get a select few movies started. Most of the movie links in the “free entertainment” did not work.

I flew Business Class. Rory, one of the Cabin stewards, was attentive, explained the menu, provided appropriate drinks. was

temperature was too cold there should be free blankets, seat are very uncomfortable, entertainment is limited.

Basic service for a decent price, all amenities are à la cart

It was extremely cold in the back of the plane. The seats are uncomfortable and space very small. Crew was excellent as usual.

The plane needs upgrading, the seats are uncomfortable, we are a family of three and they split us and did nothing to group us together, and the food is horrible compared to other airlines bu

Horrible almost missed my flight because my 1st flight was delayed. Airline crew is so unprofessional. The people on the plane do whatever they want kids running screaming. Will never fly this airline again Suitcases never arrived

Boarding was odd. Gates switched and had to take a bus to the plane. Luggage got lost. Still waiting on one bag. Flight itself was very nice!

Do Not Fly Iberia. Horrible experience. Iberia changes things at random -like the date of the flight and seat you have bought. After buying my flight, they contacted me and told me I had to return a day later. Then when I was boarding the flight, I discovered they had changed my window seat in a row away from the wing, to an aisle seat in front of the toilet! The worse seat on the plane. But it wasn’t just me- a family was scattered all over the plane. I was able to trade my seat because a father was separated from his son. Unfortunately the seat was the window seat directly over the wing, the loudest seat in the plane. I couldn’t sleep, even with noise cancelling earphones. Also, I ordered gluten free meal-which was tasteless and gave me cramps.

I have nothing but great things to say about the crew of the American Airlines flight from Madrid to Dallas. They were fantastic! I do, however, have some disregard for the flight attendant that was late in Dallas, causing us to further delay the boarding of our flight to Portland, and leading to the eventual cancellation of that flight. Because that crew-member was so late, we got caught-up in a weather-related ground stop, eventually causing our pilots to "time-out". So we couldn't get out of Dallas. We would have departed DFW on-time (and before the arrival of the thunderstorm) if not for the lateness of that crew member. The whole time the pilots couldn't tell us whether the flight would be cancelled, and that they couldn't get any information from the airline. By the time we knew the flight was cancelled, all of the flights for the following day were full. So, we didn't even get offered a viable option to get home. The American Airlines customer service desk at DFW was grossly under-staffed. And there were several people who waited in line for four-hours before being helped at that desk. We waited in line for almost 2-hours, until I was able to speak with a customer service agent on the phone (after being on-hold for over an hour). So, once we knew the information about how to get our bag in PDX, and that there weren't any options for flights the next day, we left the line & began searching for another way home. We eventually had to purchase a ticket home on a different airline, in order to get my wife to work on Monday. And we are pursuing a refund of that DFW-PDX leg of the journey. The good news is that the late flight attendant's hair was perfect. And she looked fantastic as she departed the airport & headed back home, while we all hunkered down to sleep in the terminal for the night.

One of the crew members hit me with the car and not even says anything

They need to start flying on time. We lost 2 days of our time because they delayed flight both ways.

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.

Some how my flight was canceled, neither BA or Justfly.com accepted responsibility. I only found out about this the day before when I tried to check in. I had to book another flight which due to the time ( day before) cost me $300 more. I was still receiving notifications about the flight even when I was on another flight from you. So no my flight to London was not good.

We had a pretty good experience. Enjoyed both the flights. Crew was very good and helpful.

They issued seat assignments and sat my 2 year-old in the row behind me, separate from me and my daughter. Communication/ customer service was terrible. They told me to change it in London, then in London, they told me to talk to the cabin crew, then a supervisor came and stuck us in the back of the plane when we were supposed to be in row 25. Overall, they need to really work on their customer service. Additionally the food was terrible and they ran out of meals and didn’t have any kid options. To top it off there was no in-flight entertainment for the first hour of the trip.

We missed the connection because we had to wait for a shuttle from the plane to the Terminal. Also, we needed assistance and none was available.

When we arrived at the airport - 1st step - printing out your boarding pass - no issue. Not long lines as these machines. 2nd step - processing your bag drop off. There was only one associate there to help 10 kiosks. We had a family in front of us for 20 minutes trying to work on the machine and figure out every step for 4 pieces of luggage. My husband alerted the associate who was able to assist the family. Highly suggest that there are more associates to assist in this process. Besides this issue, security check went very quickly. Our flight was direct to Philadelphia. We had to carry our bags down two flights of steps, then out to the tarmac to a bus, then carry our bags up two flights of stairs to the plane. No one on the flight was expecting that long trek. I could see some people were struggling a bit. All in all - great flight crew, plane was clean and food was great!

There were no gluten-free vegan options available, so food was very limited on this flight, and some of the crew weren’t especially helpful about it. To make matters worse, a passenger was sick on board, and although the area was cleaned, the smell lingered for the rest of the journey. On top of that, we ended up circling for an extra hour, which only made the unpleasant situation drag on even longer.
