Much better, not their fault but my plane was so delayed causing me to have to take this airline rather than my earlier connecting flight

Much better, not their fault but my plane was so delayed causing me to have to take this airline rather than my earlier connecting flight

TERRIBLE! Staff was unfriendly, rude, and demeaning. One flight attendant touched me to grab the complimentary blanket off my neck because I couldn't take it home, while a bunch of other people took theirs home. I have never been so ill treated. I am not happy at all. And flight was delayed, no information until short notice for everything. Lost an entire day at my destination. I expect a full refund for that experience. Never will fly with them EVER again

All was good. I think the back of the plane should be boarded first. It would be faster. Minimal waiting time behind passengers loading their carry on baggage.

My return flight has been changed to JFK from EWR without any notice or reason

Flight was delayed 3 hours. Pilot cancelled flight under 4 people volunteered to change their seats to economy from business class.

I paid for wifi and it worked about a total of 5 min. Feel ripped off

Overall, this flight team did a fantastic job. They came often with the water, coffee and tea. There was no meal choice in coach, but the lasagna lunch was decent. The sandwich snack just before landing was tasty. The baggage bins were large, so no trouble holding carry on luggage.

My seat was not the one I paid for, the crew was very curt, and the cabin was extremely warm.

Old plane with terrible business class seats - good food and service. Boarding was a joke with business class boarding last.

Best airline to travel on a budget- really like their reasonably priced access to the SAS lounges where available.

The flight was half full and I presume that the next few days are even less busy not sure why they are still charging a premium to change a flight.

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 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.

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.

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 did not get to my Miami destination/home. I am waiting for it 24 hours 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.

As with every airline the seats are not built for tall people.

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

An average flight experience. For our transatlantic portion, they provided a main meal and two snacks. However, the food was not very tasty and the drinks far too small and infrequent for such a long flight. The regrettable part of the flight was that the toilets were extremely filthy. I feel this is unacceptable.

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.

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.

Another 35 min delay landing No apology no communication or acknowledgment about this

Try to humanize onboarding and take AI out. It's embarrassing and useless

Disappointed everytime. The app doesn't load the boarding passes. They have lots of agent that seem to be busy doing nothing with a long line waiting to get paper boarding passes. Food choices are poor. Entertainment is less than entertaining.

Horrible experience. Nothing to give to kids to keep them entertained.

Trouble keeps changing the time and I was booked different flight without knowing it was bad experience

Overall good experience. Polite crew. Good foodandentertainment. Seats are small and bit congested though.

I ended up buying (for $340) "extra space" seats because I my flying partner was given a STY boarding pass, leading me to conclude that she was on standby and that we had to buy seats on the flight. I later learned that the flight was not sold out and that we could have gotten on as usual. To be honest, I felt swindled.

This flight is always a cramped bus. The gate area was inadequate and announcements were hard to hear. The flight was delayed 45 minutes to an hour by a broken aircraft door, making our total delay from Vilnius 5 hours.

I'm Canadian. I have the unfortunate experience of pretty not having the choice to fly with them. THEY ARE TERRIBLE.

didn’t even get to go one of my returning flights cancelled and I wasn’t even in their system, vacation ruined thanks for nothing

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.

In economy and food was ok, but with limited leg space (and I was in a 2 seat configuration) it was difficult to eat with a tiny seat tray. I spilt wine on my trousers. First time on British Air (I usually fly Turkish Air) and in a 777. Heathrow was pleasant but changing terminals awkward.

Starting with the flight Cairo to London the plain was so poor no entertainment at all uncomfortable seats although it’s 5 hours long,then an American airline plain took me from London to Miami it was a bad experience the crew most of flight time not available and they asked us to help our selves for any snacks if we need. From Miami to London actually was perfect flight with a huge plain and perfect crew but from London to Cairo was horrible plain with stiff fixed seats not movable no entertainment or wi fi very poor Menu which is unacceptable for a business class

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.
