Great flight- smooth, nice crew, nice clean aircraft, departed a little late but arrived 10 early.

It was listed on my ticket as Finnair but there was no indication that the flight was Finnair. In fact the number was even different. There were no employees there until exactly 2 hours before so we had to wait in line at Iberia and hope

I booked the flight with Finnair, which made the arrangements for downloading a boarding pass unnecessarily complicated. I wouldn't do that again. Instead I'd book direct with AA.

Flight ok, but me and other two passengers didn’t have connection with the entertainment in our seats. So, no movies, no games, no music… for 9 hours. The crew just told us that there’s nothing they can do but I noticed during the flight that there were empty seats, so they could have offered to us to change seats. Customer service could be better.

Had a nice flight to London on BA will fly with them again in the future

Finnair cancelled my flight 12 hours prior to leaving for Helsinki. They stated there were mechanical problems. I had to scurry around to find a new flight that would meet my needs for arrival in Helsinki. Luckily I was able to find alternate transportation through Lufthansa/United.

I’m very disappointed, to fly into an airplane for 10 straight hours, and not having a TV even though when I put the ticket I was told that I will have entertainment for the TV. Very disappointed.

Helpful steward. Allowed me to move to some empty seats and I was able to get some sleep. He also had milk for my tea. Americans don’t realise that cream or half and half ruin tea.

Security was a mess at the Helsinki Airport. But I was delighted by the connecting flight waiting for us for JFK.

Very rude hostess. She embarrassed me in front of others. I went to sit after taking off in a different sit in the same economic cabin. Was the area where doors are. She come to me very laud and said: go back to your sit those sit are more expensive.wow! No diplomacy. Flight was super full except 3 of those sit. The only person in that row later during the flight occupied all sit laying down!. Once more disappointed at American Airlines. Early flight they lost my luggages for 4 days. Never refund money for replacement for some of essential items purchased..when I booked the flight I thought was Finlandair. I

Was as expected. Good leg room on planes - much appreciated.

Smaller, regional aircraft limits amount of overhead luggage space. At least there were jetways at both BNA and PHL. First class food service was minimal with the usual assortment of packaged snacks (nothing creative) and no handiwipes. American tries to turn around aircraft too quickly without enough time to clean the planes. WIFI service did not include TV programming.

6 plus hour delay with no explanation. No wheelchairs to transport us on arrival. Very disappointed.

Food choice is limited, entertainment better than average, seat leg room terrible

While I received notice that AA 478 was delayed, the flight departed PHX and arrived PHL more than two hours late. The first class cabin service was mediocre; there were no pre-departure beverages offered; there were no warm mixed nuts served with cocktails; there was no personal greeting to me as an Executive Platinum member by the first class flight attendant. While the flight operated safely, its arrival at 0219 in the morning in PHL ended a very long day. I do not feel that American provided first class service.

My baggage went to Dallas and not to Philadelphia. Do I need to add anything else?

Late arrival due to gate being blocked by stalled truck

delayed delayed delayed. was supposed to have a 2 hour layover and very nearly missed my connection.

We truly had not one problem. Nive enough to receive an upgrade. Flight attendants were extremely friendly and cheeful. Gladly will continue to fly American.

Flight operated on tie. However, the in-flight entertainment was inoperative. No special recognition as an Executive Platinum member.

the room on the plane was good but that is because flight not sold the other three seat and I had room. the food in terrible.

First the price I paid was excellent, my flight was full, but my seat was roomy. The one downside to the experience was they had games on the entertainment console. The guy behind me poked at my head about half the flight. I hope they get rid of this feature.

There were a lot of empty rows. As a single passenger I should not have been seated with 2 others. The WiFi didn’t work. The Kosher meal was awful.

They should. Heck planes more often not when they are suppose to be leaving causing delays

Thankfully not a full flight so although my headphone jack wasn’t working 100% on my window seat, I was able to move to the aisle seat. Food was fine, nothing great but tasty enough. Crew were friendly and made enough rounds. Always have a decent experience with Aer Lingus

Crew was fantastic got lovely food and plenty of water. Entertainment was good. Never had to ask for anything. Left on time and got to Seattle early. Luggage did not take long either.

Great hospitality and service! Seats are better cushioned then some

Great hospitality and service! Seats could always be cushioned better.

Customs is always a challenge. The customs officials were real humans, which was nice-not robots programmed on angry 😊. If you’re in a hurry to get through you’ll be stressed out. Allow yourselves plenty of time and it will be a stress free experience.

I got rerouted to another flight/city because the original flight was late and I would not have made my connection. I had to wait an additional five hours (no compensation) for the new flight which was also delayed because the computer was not working. Arrived at my final destination after nearly 20 hours of travel only to discover that my baggage had not arrived with me. Two days later and still waiting for my baggage. Customer service has been incredibly unhelpful and even hung up on me because I dared to ask for them to have someone call me when my bag arrived at the airport. No one apologized to me for what I experienced and they were dismissive of the fact that I have absolutely no clothes or toiletries. Absolutely awful, disorganized and stressful experience. Am dreading the return flight.

I would not fly with BA again. Packed in like sardines, constant request to turn down air conditioning due to freezing cold for hours and the food was pretty to look at but tasteless!

My wife and I paid for seat selection to be together. My wife and I were on separate rows and the excuse they gave was they changed the plane. Also, I have celiac and asked for a gluten free meal in the ticket profile which they did not have.

Seats, comfort level ugh. Crew was not attentive, only to coach

Pros: they tried to accommodate bc they forgot my gluten free meal Negatives: The flight was freeeeeezing Iberia didn’t communicate my gluten free meal

This flight was a code share for both Iberia and American Airlines and run by what I assume is a charter company Level. It was difficult if not impossible to get a seat assigned, check bags or use any customer service functions. I would skip it!

Both flights were delayed. I lost my connection on the way back. No voucher or anything was givenx I had business ticket and no support to make it on time. I got to the door running 5 min after they close. Food really bad. Breakfast in business was worst that I what I remember in economy. Even though I have accumulated many miles, I don’t think Inwill keep buying Iberia. I am a frequent business traveler.

I called prior to flying to confirm our baggage allowance which was 5 bags. On our outbound flight thee were no problems. On the return flight we were charged for each bag totaling $400! We are working with customer service to resolve the issue.

Late boarding. Delayed departure leading to rushed connection at Madrid Barajas. Not necessarily Iberia's fault but delay loading cargo didn't help.

Everything was fantastic except the Iberia website and app… they left a lot of questions and induced much stress. But once on the plane, all was awesome.

I needed assistance and the staff at the airport and crew were very helpful and polite

Offered vegetable curry when it was actually tofu which I don’t care for.

The flight was good the crew excellent…but take off delayed three hours!!!

Both mine and my husband's chairs were broken. Also it took 2 hours to get our bags after our flight which was wild.

perhaps eye contact with the cabin crew, instead of abruptness and an impatience to serve.

Not enough trash pickups throughout the flight. Everything else was great.

Overall good, the gluten free food is very hit/miss though and you must tell them you have an allergy days in advance.

All was good. The headphones they supply are of poor quality. The food is good but too much dairy.

Seating space was crowded and I am a very small woman.

I sat in the last row of seats. On an 8 hour flight they allowed folks to stand and talk and drink in the back area near the toilets the whole time. They were at times loud and in the way. It was a little annoying. The crew on this trip were pretty mediocre and the plane was littered with trash when we disembarked.

Boarding process needs to be improved. Business class passengers were told to stand in the economy line and vice versa.
