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

Sorting on line would have been appreciated Onward information on flights missed No ability to get seating arranged before we got to gate Very unfriendly at gate

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

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

The crew was very good, excellent, they help me with my needs.! Food was not that good.

Good flights. Departure and arrivals were on time. DFW was a little problematic in that the Skytrain without prior notice bypassed the Echo terminal so that delayed my arrival at my connecting flight.

Because I can’t stand very long in one place, I was allowed to reword.

The return trip was a customer service disaster. American Airlines needs an overhaul of how they treat their customers.

We were delayed bc ground crew gave the flight crew the wrong paperwork. We taxiied to the runway then back to the gate to get the correct paperwork that no one bothered reviewing the first time we pushed back. Boarding was rude and stressful like it always is. Gate agents and flight attendants are all over 55 years of age, embittered by years of underpayment From AA leading to their passive agressive bitchiness for no reason.

Was flying in premium eco and there were around 5-6 movies I wanted to watch and none of those could I play for some reasons. Not just me we checked w the person sitting next to me. Few of the movies were only playable :( Also that was not great that we couldn't upgrade to business however tried to, many times before the flight :(

You cancelled my flight by email then made it very difficult to get in contact with you. Then put me in a flight with a long layover in Mexico returning to the wrong airport in uk. Mind blowing my stressful. I missed see my grand dad because of you.

This was not the BA business class it used to be. Mediocre food, attendants seemed stretched thin. All the little luxuries that used to make BA business fun were missing. Flight delayed and the explanation given was they forgot to pick up crew - I hope I misheard! Transfer in LHR “sticky” - we thought we had way too much time at 3hours but it was needed. Next time will try different route.

Flight from Phoenix to London was very quiet. Excellent space available for comfort, couldn't fault

Food was very average. And top up drinks offer was absent. For a 11 hour long flight that should be the minimum. The crew didn't want to be there. I understand it was new year day but given they had signed up for it

It was my fault choosing the seat nearest the entrance but it was ok.

Short flight so not much to rate. Surprised I had to pay for a soda.

Nice to be on a flight that wasn't fully booked so there were only two of us in the three seat row.

The only problem was there are games on the entertaiment system. The guy behind me played poker the entire time and poking the back of my seat. I hope they remove these.

Very good need to offer better choice of food for business

Great travel. Wonderful experience. Hope to do it again in the near future. God willing

Aer Lingus doesn't have plug ins for devices at each seat. They also did not give me a dairy free meal as requested and confirmed by staff. It was as if I had not requested anything. Otherwise, they were great!

The transatlantic flight was wonderful. The regional reminded me of jet blue. Crazy and packed. Not enough overhead space and tough on elderly.

All OK. Food, best bring your own. Even a BigMac will be better.

Always find Aer Lingus reliable and good value for money. Food on this flight was pretty basic and the headphone Jack at my seat only worked for one ear. Little disappointed in movie selection, limited on recent releases. Staff are okay - but I always buy a cheap ticket so not like I expect first class opulence anyway!!!

Great hospitality and service! Seats are better cushioned then some

I’m hoping for WiFi included. Everything else was very good

Rude security cunts. However the lady that issued my boarding ticket when I was flying back from New York was lovely & helpful!!

Appalling! The flight was delayed by 3.5 hours and the American Airlines staff at the airport where nit very helpful. Once boarded, the flight crew were unhelpful, the food was poor and the aircraft was tatty.

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.

Everything was great, except the food, which could have been flavorful.

Took too long to tak off but besides that it was good

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

Seating was very tight and not comfortable. Would rather pay extra to get more leg room. Overall, the flight was not as nice as expected. It’s comparable to flying Spirit Airlines or Frontier airlines in America. Even as a budget airlines, Iberia should at least serve water or light snacks, especially for international legs, no matter how short the flights are. We were flying from London, Heathrow to Madrid Spain on a 2-hour flight without offering water, unless you want to pay for the water.

I've done hundreds of flights in my life, and this flight was one of the best I've ever taken, From beginning to end, everything went smoothly, professionally, and with a smile and friendly attitude from all employees I interacted with. The food was delicious (and free), as were the drinks. There was just a genial and effective way in the way that British Airways organized the flight -that reminded of days in the 70's, 80's, and 90's, when flying was a fun, and exciting adventure. I enjoyed and had confidence in the abilities of the flight crew, I'll be flying British Airways several more times this summer. Thank you so much for the great experience! Cheryl Olso

Terrible! I missed my flight to my final destination and British airlines and American Airlines keep pointing fingers on each other’s. Nobody wants to take responsibility

Overall, terrific service, accommodations, and experience. Only reason comfort was rated lower was because it was difficult to keep a comfortable sleeping position for the overnight flight, but I also had an economy seat.

Very cramped seats in economy, difficult to get comfortable with your legs and feet and back. The seat width is ok but I’m average size. Food is HORRIBLE. Crew is friendly. Delays and very tight connections made it tough for navigating. We would have missed our connecting flight if it wasn’t delayed too. The terminal transit was slow and normally every 10 minutes before 8pm, after 8 pm is every 30 minutes!!!!! No free wine or drinks!! Below average attitude.

Leg room was better than expected. Lavatory’s were easy to access.crew was grea!

Horrible seat allocation. Boarding was slow. Food was average and so was entertainment. The TV terminal didn't work and so had to use remote.

Lost one checked bag.and wasted 30min waiting and filing missing baggage report. Very unsatisfied.

This was an American Airlines flight. The crew were very unhappy and quite grumpy. Abrupt to the point of being rude. The food was dreadful. Indeed the breakfast was in edible. I will avoid AA at all costs in the future.

Fare was much lower with a layover in London as I was able avoid numerous landing fees that would have been added to the ticket price had I booked a direct flight to Amsterdam.

We have business class seats from Los Angeles to London. The crew is friendly and provided great service. The flight was very comfortable and very smooth. Will use this airlines again in the future.
