Make sure you are at the airport at least 3 hours early to ensure that you can check in, go through security, and so that you can find your departure gate within plenty of time so you are not rushing.

By your own food and have your own music. Upgrade your seat if you have the funds!
WendyFlew with IberiaLHR-PITJul 2024
This is a good service to a smaller gateway airport. It's usually full. This service is why we selected BA. If you've prepaid for your seats be prepared for them to switch the plane configuration and reassign your seats. You'll have to apply for this refund too since it's not automatic. These refunds should be automatic not a chore for you to get your money back, especially when you have selected seats you personally want.
Anne KatherineFlew with IberiaLHR-PHLJul 2024
Need more snacks. As meals not big and need more to eat Also take own water on board as not enough drinks offered from cabin crew - can feel dehydrated during flight
SuzanneFlew with British AirwaysLHR-PITMay 2024
1 - bring a portable battery backup because you can't rely on the outlets at your seat to be working. 2 - download movies/shows to your device, because you can't rely on your headphones or screen to be working. 3 - download any work, as possible, to your laptop, because you can't rely on WiFi to be working.

Boarding uncomfortable. Stewardess said I would have to check my carry on as there was no room in the overhead bins. Another passenger helped me find a spot.

Boarding uncomfortable. Stewardess said I would have to check my carry on as there was no room in the overhead bins. Another passenger helped me find a spot.

Any flight that lands safely is a good flight. However our leg from Helsinki was delayed 1 hour with no explanation. The delay would not allow us to make our connection to Cincinnati. I was informed by American Airlines that our Cincinnati flight was rescheduled for the following day. I immediately made a non refundable hotel reservation in Dallas. Upon exiting the plane at Dallas I was given a hotel voucher. Nice, but I can't get a refund on the hotel I booked. A little communication would have been helpful. Food on Finnair is below quality of Korean Air.

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

Good crew and a great experience. Only good things to say.

Staff at the gate were incredibly rude, hostile and threatening. Never fly American Airlines.

Timely boarding process, made up for lost time even after a lengthy wait for de-icing

My seat was wonky...hard and not much padding. I sat next to the Jumpseat for the flight attendant. Thoroughly enjoyed not have a third seat in that row! Flight attendants were amazing. I couldn't answer the "food quality" question as there is no food served on my short flight. I commend the pilot as I know it was super gusty when we landed. Thanks

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

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.

My flight attendant was attentive! The elderly person next to me was flatulent and the flight attendant could see that I was in distress and brought me some face masks

Great thanks - a whole row to myself. Good food but film selection not great.

Overall flight was as expected. It would have been better with a couple options for snack instead of only one item and if there was a TV or music as option. But overall satisfied.

This flight was delayed and caused me to miss my connecting flight from New York to Boston. I had to rent a car and drive myself home to avoid waiting another 5 hours in the airport.

Flight was cancelled. There were no Aer Lingus reps to help. I had to rebook my flight and find a hotel. Still had nothing from the airline.

They couldn't do through check-in for us. They took 2 hours to issue just one leg of the boarding pass. They had no idea to handle the case of passengers who travels to USA via Dublin airport. we had tough time time Dublin airport as boarding pass for the US flight was not pre-issued. Hope Aer Lingus will learn to handle such cases which they couldn't learn in in the past 50 years of the service.

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.

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.

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.

At Barcelona, you have to get your passports checked before going to the E gates so give yourself time for that. The restaurants around the D and E gates are really limited compared to prior to passport control. On boarding, the gate staff tried to charge me EUR100 for my carryon, saying it was too big. I put it in their ‘measurement box’ and it fit with the top slightly protruding where the handle was. The gate staff then said my bag was ok to carry and put an ‘approved’ tag on my bag. I was bussed to the plane I boarded a ‘Level’ carrier which I had not heard of before. If you booked through a code share like American, you will be served food and alcohol on the plane. They do not provide complimentary ear phones or blankets. The internet was free but only for texting. WhatsApp worked but Spotify did not. Entertainment choice was adequate, movies were old and selection was limited. On arrival at LAX, my checked in bag was damaged as the wheel was broken. I am taking this up with Iberia. Their website and customer service was moderate in terms of user friendliness. You have to have all your documents and prepared to be patient and persistent. Let’s see how this goes. All n all, for the price I paid, I would recommend Level.

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.

They did not provide free WiFi, It could be purchased for, I think, around $25, This seemed excessive.

Reliable, great value, but not outstanding in any aspect. This is similar to the experience you get in most international carriers like Etihad or Delta.

Flight got diverted because of an emergency and the crew were fantastic and probably saved that passenger’s life. While in emergency landing some measures could have been taken to prevent additional delays. In general not great experience with BA. I used to fly BA years ago all the time, very disappointed by the whole experience, seats were tight, bathrooms tight.

Business class area too small and chair and equipment not comfortable .

Lost my luggage in London Was double charged for luggage

Boarding could have been better organized. The one member of staff disappeared for a while so boarding by group relied on honesty.

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.
