Wonderful as usual except for other guests that were unruly and not kept in check by the Crew.

This was an overnight flight. There was no meal service in first class, just a simple snack basket was offered along with beverages. There should have been some type of continental breakfast prior to arrival in PHL. As an Executive Platinum American Airlines Advantage member, I received no name recognition from the first class flight attendant. When disembarking at PHL, the flight attendants were more interested in their cell phones than saying "thank you" to the passengers as they disembarked.

the pilot that landed this flight in Philadelphia did an amazing job, the weather was absolutely terrible and we landed safely.

The flight was just perfect! We left a few minutes early, had a smooth flight and fortunately had landed before the terrible accident that took off from North Philadelphia airport shortly thereafter.

Timely boarding process, made up for lost time even after a lengthy wait for de-icing

My seat was wonky...hard and not much padding. I sat next to the Jumpseat for the flight attendant. Thoroughly enjoyed not have a third seat in that row! Flight attendants were amazing. I couldn't answer the "food quality" question as there is no food served on my short flight. I commend the pilot as I know it was super gusty when we landed. Thanks

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.

Flight was on time Crew was not. very friendly I paid for premium class and It wasn’t too much different from coach

I chatted with the captain before the flight, and similarly during the welcome announcement, he warned of a turbulent flight that may impact the in-flight service. However, once at altitude, he announced that the weather changed and he immediately turned off the seatbelt sign. But it appeared the cabin crew had already decided to take off this flight. They remained seated and then just chatted in the galley. The flight was fully catered, but only first class received service.

My flight attendant was attentive! The elderly person next to me was flatulent and the flight attendant could see that I was in distress and brought me some face masks

Front desk was closed at 6 pm, I was unable to get my boarding pass and as such missed my connecting flight home.

I wish they could put the pre-tsa check on the tickets or global entry.

We upgraded to Business class paying approx. $1,300. Despite the upgrade, we were still required to pay an additional €70 for a checked bag. Furthermore, we were informed that another €70 would have been charged for our carry-on bag, as it was 3kg over the limit. To avoid this, we had to move clothing from the carry-on into the checked bag, which was both inconvenient and frustrating. Given the significant amount paid for the Business Class upgrade, we found this treatment to be quite appalling and disappointing. We expected a higher level of service and consideration for our luggage, and this experience did not meet those expectations.

At Barcelona, you have to get your passports checked before going to the E gates so give yourself time for that. The restaurants around the D and E gates are really limited compared to prior to passport control. On boarding, the gate staff tried to charge me EUR100 for my carryon, saying it was too big. I put it in their ‘measurement box’ and it fit with the top slightly protruding where the handle was. The gate staff then said my bag was ok to carry and put an ‘approved’ tag on my bag. I was bussed to the plane I boarded a ‘Level’ carrier which I had not heard of before. If you booked through a code share like American, you will be served food and alcohol on the plane. They do not provide complimentary ear phones or blankets. The internet was free but only for texting. WhatsApp worked but Spotify did not. Entertainment choice was adequate, movies were old and selection was limited. On arrival at LAX, my checked in bag was damaged as the wheel was broken. I am taking this up with Iberia. Their website and customer service was moderate in terms of user friendliness. You have to have all your documents and prepared to be patient and persistent. Let’s see how this goes. All n all, for the price I paid, I would recommend Level.

Was very unhappy with the entire process, from check in to boarding to the comfort of the flight. Did not enjoy the flight on Level.

Overall a great. However, the seating is way too narrow, for guys with any shoulder width. Luckily the crew moved the guy next to me, or it would have been miserable.

The staff on our flight from Charlotte to Boston were very friendly.

Alaska located my mother, aware that she had mobility issues and they seated her closer to the door. She and I were seated together so I felt more secure to be able to assist her. The desk attendant reviewed what steps to take when boarding. Allowed us to board first, we loved that. I was allowed time to help her board slowly, seat her, put all her things in their place before the crowds came through. These small details made me want to travel Alaska more when possible.

The flight was decent. I purchased my flight through Iberia, traveling with my elderly mother with mobility issues. I try to pay for luggage and seats online prior but Iberia website directs me to AA website. AA airlines website does not recognize the record locator. My mother and I are separated and each get a middle seat. She is seated the furthest away from a bathroom. I had to sit behind her to see her wave at me to use the bathroom. Lights out on the flight and I could not see her wave and she is not tech savvy to push an attendant button even though I showed her how. The attention to this detail puts AA at the bottom of my list when traveling with my elderly mother. Bad execution and handling when servicing those with extra needs due to mobility. I could not get her to the bathroom because she’s slow and she had to wait for me to get up from my middle seat then move her out of her middle seat. She had an accident which required that I hel her clean up before taking her back to her seat.

The flight staff was excellent, one of the best I've had. Food and wine was very good and seats very comfortable. Luggage came out pretty quickly too considering the number of passengers. Also, excellent internet. The only thing that could have been improved on was the choice of movies -- kind of limited and not great selections.

Boarding is a mess. They never check group # so lots of people crowding in. Comfortable seats this flight. I had an empty seat next to me, very convenient. Food was really not good, but I was starved. The pizza snack thing was horrible. Crew was grand. They really make it enjoyable.

Too much long line at the TSA and Security. Prepare for long walk for baggage claim.

Crew very helpful and friendly. Food is so so. Main meal is not always the best. Did have a choice of a snack part way which was either a cookie, corn snack, or similar. Second kind of meal was basically like a pizza pastry that really wasn’t a favorite but probably a European snack? Screens and selections of movies, tv and such were good. No WI-Fi unless you buy so no free texting or such on the long flight but I think that might be any overseas flight.

The boarding process was quite loud and chaotic. The flight attendants kept barking over the PA system about people needing to only stow large items in the overhead bins. During the one and only service, I was hit by the service cart. At the same time, a passenger was returning from the bathroom and the crew definitely saw him but stopped a few seats short of allowing him to sit down before starting service and made him wait a good 10 minutes before passing his seat and allowing him to sit down, after which he had to ask for his snack and beverage or he would have been passed over. Neither flight attendant thanked passengers as they left; in fact, I did not see them again once the plane door was opened.

Flight Attendant Karen Lynn was an absolute delight. She assisted in every portion of the services provided throughout the flight, aided with any and all concerns expressed by passengers, and even helped comfort an upset child who was one of five of a traveling family. This quality of service is what keeps me coming back to American. Thank you!

The worst, flight cancelled because the aircraft was not full. Heathrow ground crew totally not helpful and arrogant. Lady proposed us flight with 40min layover instead of direct and said it is our problem of course she was unable to do anything as everything was beyond her control she claimed. after calling on hotline another flight was booked. Flight was cancelled last second so we could not take direct from Zurich but we had to stay overnight in London.

The seats in row 31 are terrible and small and uncomfortable. Don't ever sit there. The window seat is so close to the curve of the plane is so annoying. I paid extra for this seat and I hated all 10 hours in it.

Food was terrible , crew were excellent , IFE was dire . Overall comfortable seat and cabin. Nothing special .

If my tv wasn’t broken and I wasn’t in a seat that didn’t allow for sleeping

Delayed flight due to lack of crew caused me to miss my connection
