We were delayed 3x and because I didn’t purchase my tickets directly from United Airlines I was told I Have to take care of it myself so I called Underpricer and they helped me but before I changed my flights I took the risk of sticking by what my tickets were and was lucky to have gotten on the original all flight with only 15 mins before take off. not sure if I will do this again

We were delayed 3x and because I didn’t purchase my tickets directly from United Airlines I was told I Have to take care of it myself so I called Underpricer and they helped me but before I changed my flights I took the risk of sticking by what my tickets were and was lucky to have gotten on the original all flight with only 15 mins before take off. not sure if I will do this again

The flight was delayed so the people from a late connecting flight was able to still make the connection.

HORRIBLE WITH THEIR WEBSITE!!! WORST WEBSITE IN THE WHOLE AIRLINE INDUSTRY

The planes are so dirty! Food crumbs and finger print smudges, Dust over the vents and carpet stains. It’s disgusting.

Everything good until we waited for jet bridge at SFO. Then pilot gets on speaker & said it won’t reach plane- too short, need to go to different gate. Then 5 min later, adjusted plane/jetbridge & all ok?!?

Gate got changed about 4 times. Very confusing and very crowded. If you don’t have wifi to help get updates, you can be in deep trouble.

Did not even get on board. Was told I needed an esta agreement. Was not aware of this when I booked the fare and not told about them

David went above and beyond to make our flight the best that it could be

Was a pain having to leave the plane and reboard but glad the plane was fixed

How badly can you screw up baggage claim? We were told to go to baggage claim too for our bags from this flight. Another flights bags were there. They finished up. More bags from a different flight arrived. Our bags did not Finally the baggage claim belt stopped working and and are flight was still listed on the arrivals for that baggage claim 2. And then nothing It turns out that they had been delivered not only the United baggage claim but far away on a Delta baggage claim No I never told us. It was only the people looking around who had been on the flight But I’m sure there was plenty of time for the employees to raffle through the bags and steal whatever they wanted

Flight attendant walked away once they landed and we were forced to wait another hour after an already 3hr delay.

No overhead space so all carryons were checked. No internet.

The flight was on time and everything went very smoothly.

A thousand choices for movies and nothing to watch. I avoid 'R' rated shows and others with violence and sexual content, which results in a handful of flicks to view and I have them already.

I think I paid for an extra legroom seat and to be honest, there was not a lot of space available for my not very long legs. The flight was totally full and the staff did everything possible to meet the needs of all passengers. My only concern was for the size and spacing of my seat.

Flight was on time Crew was not. very friendly I paid for premium class and It wasn’t too much different from coach

Two issues. The plane was old and dirty. The armrest looked like an old car that had the vinyl rubbed off. The Seats in these aircraft are about as hard and uncomfortable. I want to tour Italy for a month and I want to buy a one-way ticket to Thailand but I will not sit in the seats these planes have. It is seriously stupid how hard they are.

The meals were mediocre and the alcohol selection was poor. I enjoyed the selection of movies and other entertainment.

I chatted with the captain before the flight, and similarly during the welcome announcement, he warned of a turbulent flight that may impact the in-flight service. However, once at altitude, he announced that the weather changed and he immediately turned off the seatbelt sign. But it appeared the cabin crew had already decided to take off this flight. They remained seated and then just chatted in the galley. The flight was fully catered, but only first class received service.

they should make XXL people buy two seats. sitting next to a person that was half on my seat and could not even buckle the seat belt, so I had to lean in the isle the whole trip.

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.

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.

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.

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.

Loved it! Best airline to fly with. Nice crew, good planes, good food!

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.

Even the carry-ons were not allowed and upon getting down, we had the wait for the longest time for the baggage to put on the jet aisle. We had a short connection which British Airways kept changing and made out entire experience poor. I would never fly BA again.

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.
