All good- I love BA and the professionalism of the crew and pilots.

All good- I love BA and the professionalism of the crew and pilots.

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

The flight was Finnair but there was no indications anywhere that the checkin was for Finnair also. There was no one to ask. I think at a minimum they should list the code shares so people don’t stand in the wrong line for an hour.

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.

Tray table was filthy when I sat down. I needed to have someone come clean it because there was food and stains on it WiFi didn’t work after paying for in flight WiFi Food was terrible and was not filling at all Chicken was rubbery Flight attendant had an attitude, interrupted me and wasn’t able to answer basic questions about the food selection such as “does the chicken have red sauce in it”. If your flight attendants are not going to know what is in the meals so we can make an educated decision based on dietary restrictions, they shouldn’t be on the plane. My 1.5 year old niece was sleeping and dropped her binkie. I went on the ground under the chairs looking for it. It was at that time that she came up to me as I’m CLEARLY on all 4s with a flashlight and said “I need to get by”. I said one moment please I’m getting something from under the seat (while my head was literally under the seat). Her reply was “no you need to move now” and proceeded to almost push me out of the way. I looked up and all I saw was her toes under my eyes. When I looked in front of me, her private parts were inches away from my face. I then made a comment “you couldn’t waited 2 seconds?” and her response was, “no I need to use the bathroom”. I understand that and would never want to be the reason someone couldn’t get to the bathroom but I was under the seat. She could’ve gone around the other way instead of harassing me, basically placing her private parts on my head and borderline pushing me out of the way. You don’t pay (especially this much) for this deplorable experience. This was by far the worst experience I have ever had on American. I will be absolutely thinking twice and thrice about flying American Airlines again. I would rather pay more to fly delta because at least I know their WiFi will work and their flight attendants won’t have a terrible attitude for no reason, nor will they act the way this woman did. Unacceptable.

Great crew. Very comfortable business seats with nice bedding. Good food. We were delayed to let late passengers on the flight, but otherwise great experience.

Not being able to purchase my check in baggage online was a negative.

LATE LATE LATE!!! Plagued by late AA flights on this trip. Such a drag. This one was by far the worst.

Same basket of unhealthy prepackaged snacks (junk food) which was depleted by the time it got to my row!!

We experience delays on departure and connecting flights resulting in 14 hour to our next departure. We were accommodated with a night's stay but was only provided a 12 dollar meals accommodation. The airlines rules state.at least 50 dollars. In any case, it can not make up for the whole day missed on our vacation in Sydney Australia.

Flight from PHL to PHX arrived 50 minutes early and a gate was available. First class flight attendant Stephanie was very friendly and polite. Sanitizing wipes should be provided with meals in addition to refresher towels.

flight delayed so missed connection and this had to rebook for next day

Flight departed PHL one hour late due to late arrival of aircraft. On board services were okay. First class menu does not offer any new items; same desserts (cheese & crackers or Mango sorbet). At least there were no credit card promotions during the flight.

After sitting on plane for 7+ hours, flight was canceled. And to makes matters worse, my suitcase is in baggage hell!

Are Longus was fine. I booked thru Kayak and was unable to get my business class seat early. Sat next to galley. Crew forgot to wake me for breakfast.

I was pleasantly surprised - it has been awhile since I traveled with them - other than being delayed leaving Malaga everything ran very smoothly- yes I would travel with aer Lingus again and yes I would recommended

I loved how they arrange boarding (starting with people seated in back and moving to the front). Flight crew was very polite and welcoming. Seating was ok, I felt like there was enough leg space however it is noticeable when the passenger in front of you sets their seat back.

Flight staff very friendly and helpful where possible. Late flight and travelling with young child, cabin lights remained on for the duration of the flight which was a little disappointing considering the time of the flight. Overall very happy to travel with Aer Lingus.

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.

Delayed due to weather... fine. But then the board us. Rows 15 and back had to go down the stairs and back up the back stair entrance to the plane. No assistance offered. Then they inform us that we are delayed for paperwork for an hour. So why did we board? Then, about 45min later they inform us that it'll be another 60-90mins. Really? No wifi, no seat entertainment, no drink or snacks offered. And we were not allowed to deboard.

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!

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.

Seats comfortable on economy plus and attendants very helpful. Food was ok. Bathrooms needed servicing.

Original flight was cancelled - After waiting 2 hours for new take-off times. Then had to stand in line for 3 hours, ending at 2:30 am - to be told, " No hotel rooms anywhere in Dallas". No way for me to get any rest at DFW at that time of night.

I liked the friendly crew and desk staff, all very helpful. I was surprised and a little annoyed on my outbound flight from LGW to MCO as I had prepaid and booked my seat, which was all correct at check in on my boarding pass. when I got on the plane someone was in my seat ! I was moved to another seat. The food choice is quite limited and I feel that an option of a muffin for breakfast snack would be welcomed, not everyone wants egg or bacon wrap. The choice of entertainment is good, plenty to keep you busy on a long haul flight. I liked the option offered to have the cabin bag checked into the hold, it saved me as an older, lone traveller lifting my case into the overhead locker or finding there was no space.

My luggage never arrived in Miami; still waiting a day later.

good service from crew. Before the would have an option between cookies or nuts as snacks.. Now, there are only cookies. too bad. People who can not have sugar don't have a choice.

Flight was delayed by well over an hour. Communication was terrible.

I like the team but I don't like the food you provided with money. I want free food and free water.

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

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!

- OK plane. Basic accommodations. OK food. The digital window shade wasn't working.

- OK plane. Basic accommodations. OK food. The digital window shade wasn't working. - Expect to be woken up more than an hour before landing when they start dinging the bell and making announcements and turning on all cabin lights to serve a snack. I would prefer they remain quiet and only serve people who want to wake up.

Better food and more space in the seats. Also when doing the web check in both times I was going in to your site the minute you open it and there is not really many seats to choose only to buy!!!

It was ok, not as good as it used to be. The Heathrow connection was a disaster - complete anarchy, unknowledgable and skimpy assistance and signage. Gate crew at next flight was great, held the flight while my wife struggled through security.

It was great! The seats were comfortable, and they fed me during the transatlantic flight, something which I have been missing out on for the past 3 years as I travel to and from school.

This flight was cancelled at the last minute. We were rebooked on another flight but a day later. We lost a day of our vacation and paid for a night in a hotel we couldn’t use. The flights we were rebooked on (both American) messed up our seating on both flights-we didn’t get the seats we had paid for. All in all, a terrible experience.

Lost our bags in Heathrow, We didn’t receive bags in Mallorca for 3 days, out of a 7 day cycling vacation. Really inconvenient and disappointing!

We missed the flight to Barcelona because the flight from Baltimore was delayed. We flew on Vueling VW6653. Our luggage didn’t arrive. Please help us get our luggage. We are staying at Hotel Gran Via in Barcelona

The seats were tiny, being of a fairly petite build, I don’t usually expect to feel crammed and cramped in a seat, but I definitely was on this flight. I couldn’t even bend over to get anything out from under the seat in front and getting up to go to the bathroom at night with the seat backs reclined was nearly impossible. I had to do gymnastics to get over and out. For an airline that does long flights overnight, it’s kind of ridiculous.

Not connecting flights. Missed my flight from Dublin to Liverpool because I arrived at Dublin one hour too late. For this mistake, they offered me a flight from Dublin to Manchester. Thats great and all, but I waste time and money to commute to Liverpool. Be sure to check the time of your connecting flights, because they sure don’t when they sell it to you
