Crew were professional and responsive. Food was mediocre and breakfast could do with revampinmg

Food was very ordinary for premium economy, very small portions.
i dont know WHY they call it business class. the seats are NOT significantly wider than economy seats, they just do not let the middle seats be beepked to give the illusion of more space between passengers. the seats do NOT recline any more than economy seats either. the only real difference is the full meal served to business (vs none for economy). I would rather have a wider, lie flat ACTUAL business class seat with no food for a 3 hr flight. this was pretty disappointing to say the least.
There wore nice leather like sits, in my opinion seats lay out bit tight . Crew was great they did averything possible to make averywone comfortable as possible, food was, think worst I ever head on flight, head chicken and yellow rice. Ice cream was a nic treat.
Our previous flight was delayed but they waited for us to board.
Flight was delayed, short time connection to next flight but we make it, service was good, worth to fly just to try thair on board blueberry juce. Eccelent communication with airline.
My American Airlines flight was deleted and you guys never let me know
The entertainment system did not work. And we waited 45 minutes in our seats after we landed before we got to the gate
It was a pleasure definitely going with Iberia on my future travels
Our connecting flight was cancelled and it took us 15 hours to reach our destination.
The flight left a bit late, but arrived close to time expected…With the flight being close to full the crew did well serving drinks to all in a very timely fashion. The flight was a pleasure…
They didn't have any gluten-free snacks, oddly, which I require...or any flavored soda water or decaf tea options, which seems to be standard.
My flight back my reservations were list because they said I didn't pay my pet fee when I had a receipt
There were several issues with this flight. I have flown quite often internationally and I was surprised by the lack of presence of attendants other than meal and drink times. The food was not best but I feel that is the norm. We also had to get off the plane once in London via stairs and bus to the terminal. Anyone who had another flight had to then get another bus to another terminal. This causes me to miss my flight and have to rebook.
They could have done a better job announcing the boarding groups and asked for more drinks (water) if needed.
Very confining seats side to side. Not wide enough for any comfort.
The boarding process was a nightmare and though we were traveling business class, we were in Group 2 and the organization was terrible. The Business Class on this flight was crowded and did not feel clean and nice. Overall, I would not travel Business again on the American Airline flight through British Airways Not nearly special enough for the considerable cost .
Not too impressed with them to be honest. They had forgotten my gf meal, despite the fact that the app had notified me that it was sorted. Apparently there is a ‘glitch’ in the system, according to one of the stewardesses, and has been for a while. Also the legroom in economy is way too small (and I’m a slight person) and are very uncomfortable. An extra Internal flight I booked via the app, had not even given me the option to order a meal, so was unaware of that and left without food on a 9 hr. flight !! Don’t think I’ll use AA again after this.
For coast to coast travel the A321 and even the NEO, even in first class will never be excellent. That would take a B787 or 777 to accomplish.
Service not nearly as good as Qatar airways flights used to be on service from PHL to DOH.
Friendly crew who apologised and explained reason for delay. Good on board service. Rather cramped seating. Late departure.
Both flights late. Almost missed connecting flight and flight staff not willing to help expedite us off the plane.
during a very rough flight, I was forced to sit in a last row seat, fell asleep, and was forced to return to my assigned seat after the turbulence. The stewardess then used that seat to sleep.
I didn’t realize Aer Lingus was a “nickel and dime” kind of airline where you had to separately buy all the amenities you wanted. The push to purchase duty-free beauty products was off-putting. And our row had the least amount of leg room I’ve ever dealt with on a flight.
We couldn't talk to aer lingus we had issues with the flight change and aer lingus made us talk to kayak
Very pleasant staff, there was some turbulence but the captain was very apologetic and gave notice where possible.
Amenity kits were never handed out. There was zero friendliness and assistance by crew. Food was uneatable. One drink was offered and no wine, with dinner or before or after. Cocktails and beverages were not encouraged and when I asked for water, none was given. Poorest, most cramped business class flight I’ve ever been on.
Loved it! Best airline to fly with. Nice crew, good planes, good food!
Probably my favorite airline and way to go to Europe. Everything went smoothly! Food was tasty, crew was pleasant. Really cannot complain!
Horrible. Garbage airline. Due to the strike we got a replacement plane/crew. I didn't get my exit row seat I paid for. Food was horrible. Plane was hot and didn't have AC vents.
The connection required us to travel from terminal A to terminal E with very little time in between flights. While waiting in line, we were called to the service desk to provide our passports. We provided our passports at time of check in, assuming that American Airlines doesn’t communicate well with Iberia, this was a headache.
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.
HORRIBLE. 3 hours delayed. Crew did not communicate properly and was rude to passengers enquiring. Delay caused multiple passengers to miss connections.
1. The flight was late and I did jot get the seat I paid for. I paid for extra leg room and a window seat. I got a middle seat without extra leg room. 2. The customer service representative was not helpful. Explanation: many passengers arrived to the service desk in Madrid near baggage claim to rebook our flights. (We all missed our connecting flight due to delays in JFK). Upon arrival, ghere was one service agent and one line-business. After about 25-30 minutes the agent left and we could see her making a phone call. After about 5 more minutes, 2 other agents arrived. During our wait, another line formed for main cabin customers. We were told to go to the other line, even after waiting around 30-40 minutes. This would have been disastrous for ghose of us who had been waiting for so long. The agents need more training.
I fly to BNA with BA often and this was the worst experience. Arriving in nashville, check in was 1.5 hrs long in the queue with 1 very slow girl at the desk. When more staff came they only catered to priority customers. When all priority were checked in, instead of filtering from the top of the line they took the people from the end, the people who had been queuing for 5 mins vs almost 2 hours. The flight was delayed, for no good reason other than the staff took forever to do anything. At the gate there was zero organisation, we asked the crew what the delay was and they confirmed it wasn't the plane and it was the ground team. One of the flight attendants was one of the rudest I have EVER encountered, that man clearly hated his job, and people...I wish I'd got his name. Food was disgusting, seating was cramped. I've no idea what's changed in the last year but I'm truly shocked.
British Airways changed flight times after booking, allowing very little time between connections. We had to rush to barely make the next flight. They also ran out of certain vegetarian options during our 10-hour flight. Crew was fine, but overall a very unpleasant experience.
Being a platinum member and having reserved an exit row I was bumped into a middle seat which should not be allowed. On top we landed 10 minutes early to wait 45 minutes on the tarmac at Heathrow. I used to love Iberia, loving it less and less
I had assist travel booked in Denver to Manchester, but not listed in HeathRow, my daughter use a spare wheel chair herself for me , when going thro to board at Heathrow there was no help travel down for the ramp until a member of assistance stepped forward and insisted he would take me down the very steep ramp, seems he was the only person concerned with my safety.
Booked Economy Premium the 3 seats with my daughters and I, the seats should have been able to tilt back but it only one worked. the crew said they would report it but didnt seem both about our comfort on the return journey.#
My flight was late. We stayed in aircraft one hour 😩
Flight delay and can’t much help passenger do the change connecting flight.
5 days later I have not yet received my luggage so terrible and unacceptable
Easy and quick check in, clean and nice seats. Overall excellent experience.
The seats in airbus from LA to London are uncomfortable. They are too narrow. I am a slim person but felt cramped. The way the seats are laid out really hinders privacy. You are forced to look at the person next to you which is awkward, Also the entertainment on the same leg was limited. The crew was excellent and attentive and the food was decent. The seats on London to Delhi leg were way better. The crew again was very attentive and polite.
Great job notifying of 30 minute delay in departure. Fabulous job making up for the time and arriving as scheduled. Air travel is just no fun anymore with the extreme overcrowding, and someone needs to come up with an innovative plan for loading and unloading passengers (load all window seats first, middle seats second, aisle seats last?). Great job getting the luggage on the carousel in record time!
Although it was an overnight flight, the crew could’ve have made more refreshment passes.
All and it was good . But no one woke me when meals came around . Please have a don’t not disturb sign if you opted for that . Left very hungry missing all meals .
Late in leaving the US. Late in arriving in UK. 2 plua hous on ground in UK before leaving. Late in arriving in Spain. Didn't get our bags until the next night.
British Airways canceled my flight and I had to fly on Lufthansa the next day. What a garbage airline 🗑️
