The cabin crew really looked like they wanted to be somewhere else. They weren't really interested in providing an attentive service to full fare paying passengers at all. However the Captiain's in flight announcements were relaxed and very entertaining.

The cabin crew really looked like they wanted to be somewhere else. They weren't really interested in providing an attentive service to full fare paying passengers at all. However the Captiain's in flight announcements were relaxed and very entertaining.

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

Was supposedly in main extra (row 10), but the seat spacing appeared to be regular economy (the head rest was blue, as well - same as economy, the seats in front of us had red head rests). Otherwise the flight was good and got in well ahead of schedule.

It was good overall but the prices of snacks are ridiculous.

American was having a problem with their kiosks when I arrived which made the check-in and bag drop process unusually long. Additionally, they only had one person working check-in. Eventually, the kiosks were fixed and everything else went smoothly.

The flight got canceled last minute with no explanation or refund, I had to rebook for a different day

Flight was delayed multiple times and I chose to switch to another flight that had a layover. I finally arrived 7 hours later than I was supposed to.

This was a horrible American Airlines experience, and it discourages me from flying with them again. It may have stemmed from a mechanical delay, but it appeared that the team was unprepared to respond to the delay. After boarding, we waited an hour before finally taking off. After landing at our destination, we waited an additional hour on the tarmac waiting for a gate (at 8:00pm) to be assigned and cleared. The flight crew did their best, but they were clearly tired and also ready to be done for the day. Because of the delay, I missed a connecting flight. It was a very poor experience.

from Boston to Washington was good but return to Boston was terrible, Gate was changed and plane was so uncomfortable, I thought it would crash 🙈🤦‍♀️ also when I showed my bording pass they didn't know where to send me and finally gave me direction and at the plane they said to find free seat somewhere😬🤦‍♀️🫣

When my flight was delayed due to weather, I was rebooked to another flight since it showed that I would miss my connection. It was a lot of work to get back onto my originally connecting flight which was also delayed. That part caused a lot of stress and frustration. The ticketing agent at the desk was not very helpful.

Other than being delayed 5.5 hours and having to get a hotel because I missed my connecting flight, it was an okay flight. No in-flight Wi-Fi or entertainment.

Flight areas delayed 3 hours , train in the airport didn’t work

Really lovely trip and flight. The flight staff were so accommodating and warm throughout!

Friendly crew who apologised and explained reason for delay. Good on board service. Rather cramped seating. Late departure.

Very sad, couldn't stop crying. Was an hour delay in Ireland and when we got to Canada the flight was boarded and couldn't get on. Was the last flight of the day. Now in a hotel waiting on a stand by.I have to got o work, so I'll go first available while my son stays in the hotel til one's available

Was not aware that Aer Lingus was like the cut-rate services in the states, with no food or beverage (other then 3.50 Euro coffee) and no screens for entertainment. Was a great flight, but not much in the way of services.

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.

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.

Flight was great. Had to wait almost 100 minutes for luggage (some problem in the delivery). This may not be an Aer Lingus problem, but an SFO problem.

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.

Was very unhappy with the entire process, from check in to boarding to the comfort of the flight. Did not enjoy the flight on Level.

Overall a great. However, the seating is way too narrow, for guys with any shoulder width. Luckily the crew moved the guy next to me, or it would have been miserable.

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.

The flight was decent. I purchased my flight through Iberia, traveling with my elderly mother with mobility issues. I try to pay for luggage and seats online prior but Iberia website directs me to AA website. AA airlines website does not recognize the record locator. My mother and I are separated and each get a middle seat. She is seated the furthest away from a bathroom. I had to sit behind her to see her wave at me to use the bathroom. Lights out on the flight and I could not see her wave and she is not tech savvy to push an attendant button even though I showed her how. The attention to this detail puts AA at the bottom of my list when traveling with my elderly mother. Bad execution and handling when servicing those with extra needs due to mobility. I could not get her to the bathroom because she’s slow and she had to wait for me to get up from my middle seat then move her out of her middle seat. She had an accident which required that I hel her clean up before taking her back to her seat.

The flight staff was excellent, one of the best I've had. Food and wine was very good and seats very comfortable. Luggage came out pretty quickly too considering the number of passengers. Also, excellent internet. The only thing that could have been improved on was the choice of movies -- kind of limited and not great selections.

The plane was not well maintained. The entertainment system didn’t work properly, eg moving map. Many of the seat controls did not work. Cabin temperature fluctuated considerably during the flight. The seat allocated was poor, it was noisy and offered no privacy. The perfume in the toilet triggered severe allergies. Crew was very goid.

Seats are too tight. Small space for long flights very inconvenient.

The flight was delayed over 3 hours and at the gate, we waited for an hour to start boarding. The gate lack of communication with the passengers was atrocious and when asked they even said they didn't work there and were just standing in for someone else so they couldn't give us an information about the flight status. The crew did not offer blankets, pillows nor headphones.

I originally chose two aisle seats for my daughter and myself in the same row. We got seated in the middle, three rows apart. Both of the men sitting in front of us reclined their seats fully leaving us NO room. A totally uncomfortable flight for eleven hours.

I never made this flight but the staff helped to get me rebooked (see previous review)

The seat was very uncomfortable. It helped to use the foot rest. Could not sleep because of the seat.

The seats are incredibly uncomfortable. My luggage didn't make it on the flight from London to Nashville.

The plane itself is old and way overcrowded. The crew do a great job of trying to mitigate. It is just uncomfortable for over 8 hours, bearable, but barely. Boarding, and the baggage game, is ludicrous. Why charge extra to check bags when there is not enough room for everyone to "carry-on" and checking is needed? I do not think these issues would be different with other airlines, I believe it is the attitude that squeezes every penny out of each traveler.

Expected a lot better service paying for a business class seat. Seemed to be short on staff and did not get the service I expected.

I flew Club World and was SHOCKED at how totally absent the crew were for the duration of the flight. So much so that we received no drink service other than the post-departure cocktail and that was it. Wasn't even offered tea/coffee and the in-flight attention was so bad that literally minutes before landing the one crew member for our row was scrambling to pick up left-behind water bottles, glassware, trash. And the rest of the crew had already stowed all carts, he was cramming the trash into the lavatory trash can and was stashing the glassware frantically in the galley as we were on final approach. He was so scrambled he left two overhead lockers wide open (that he'd opened) for landing. Unbelievable!

The flight was several times changed. That was inconvenient, to sah the least.

They lost my special meal request and tried to tell me I didn't request it. I had the proof. Then they tried to get me to eat food I can't eat. No apologies

British airways keeps canceling our flights. I won’t be booking any future flights with them

I could not charge my phone the entire night or read my book, as the whole middle isle was without power.
