Ad experience - been flying many years with them but they are losing out to other carriers with their service and bagage / seating policy. My 2 12-yo kids were not placed with the parent. Absurdity.

Ad experience - been flying many years with them but they are losing out to other carriers with their service and bagage / seating policy. My 2 12-yo kids were not placed with the parent. Absurdity.

Short flight so it was okay. Nice crew, all very pleasant and professional. We were near the back in row 27 so just as we got our drinks, we started our descent so had to drink very quickly!

Our first flight was delayed so we missed our connecting flight. However it was easy to book a later flight on their app.

Klm start boarding while somw air issue in the plan

The service was great. However the lounge only gets passing grade

I appreciate that KLM was proactive in informing me of the 2 hour delay which enabled me to replan my travel. It was a bit stressful not knowing whether my connection from Montreal to Ottawa was happening. But the ground and air crew did a good job at comforting and assuring me.

Cabin crew were excellent, very proffesional, polite and friendly, in flight snack was underwhelming, a packet of cheese biscuits, im sure KLM could run to a sandwich!

This portion of the flight was through Indigo. A local carrier. So all economy seating. No real service some refreshments for purchase standard economy stuff.

Transfer at Amsterdam airport is very convenient and the airport is easy to navigate. Boarding was also quick and easy. Cabin crew were excellent and the meals were good, although lacking in options.

Overall very positive. Boarding was quick and organized. Cabin was clean and seats were reasonably comfortable. Cabin crew was excellent and the meals provided were also of good quality

It was my first transatlantic flight with Aer Lingus. Very enjoyable. Thank you for making international travel enjoyable again.

Excellent as far as the flight is concerned. Faro airport passport check was a huge delay and worrisome re missing the flight. 45 minutes there through passport control

The space between seats has reduced even further making it extremely uncomfortable. Couldn't even open the tray table properly or got compressed the moment the front guy reclined.

The seat pitch was a little tight for me, but I survived. There was a volatile, enraged passenger a couple of rows ahead of me and the cabin crew defused and resolved the situation calmly, quickly, and successfully.

My experience with Aer Lingus was nice, and I would be happy to fly with them again. However, my seat pocket had not been cleaned and had dirty wipes in it. I have flown with Aer Lingus before and do not recall anything like that happening, so presumably this was a one-off kind of thing. For the meal, I asked if there was possibly one without my allergens and the flight attendant gave me the one she thought would be fine. She did not know what allergens were in it, but when I received the meal the allergens were all listed right on the top of the package, so I was confused about why she didn’t know how to check what they were. In future, I will see if it’s possible to request an allergen-free meal ahead of time. But overall, I had a pleasant experience. My experience with Underpricer was very unenjoyable and because of them I do not plan to book through Kayak in the future. I have used Kayak numerous times, but this booking experience was so unpleasant. They called me numerous times and also emailed me to try to get me to select a seat. However, when I had a question later on, I was kept on hold for 20/30 minutes before I finally hung up. I also emailed them but never received a response, which I did not appreciate, especially given their previous frequent calls when they wanted something from me.

We booked a flight from FCO(Rome) with a stop over at DUB(Dublin) going to JFK. Boarding from Rome was kind of chaotic since the airport I guess is very small and we needed to shuttle to the airplane. The gate agent just let everyone and anyone go without using the sections so that took a lot longer than usual boarding. From drinking to JFk boarding was good and organized. Amazingly the flights was very smooth sailing and we’ve flown American big airplane to small companies before. The aircraft’s itself is on the older side, can’t complain tho because the plane ride wa smooth. For a 3 hour plane ride, nothing was complimentary. But for the longer leg of the plane complimentary snacks, meals and drinks were provided which was great. The food wasn’t bad either. I would fly with them again, great price and good service.

Comfortable trip , flight attendants professional as always. Only complaint was the food, We fly Aer Lingus frequently, this was the first time the quality of the meal was poor.

Everything went well. I made my connection which is always a concern.

I appteciate the very courteous staff. The flight was good. Something that wasn't good was that my bag was only checked as far as Dublin and I had a connecting flight to Vienna. (That was a mistake the ORD desk made.) Fortunately the desk at DUB was able to re-tag without me having to re-check in (which initially it seemed I might have to do.)

I had an awful experience at the ticketing agent stand. I had purchased three tickets, one of which I had the maiden name of a passenger on the ticket. They refused to help, assist, and actually delayed our process and had us miss an opportunity to purchase a ticket on the same flight. I was sent through multiple phone calls, none of which helped, and the person at the counter was the person who told me to both call Aer Lingus for help and was the person who said they could not fulfill my request that they were privy to from the beginning. My partner is still stuck in Scotland, racking up thousands of dollars in additional fees and tickets. I am very upset and two of my tickets went unused. I will never be using Aer Lingus ever again and I will continue to complain about them.

They were extremely unprofessional and unhelpful at check in. They did not understand laws related to Spanish residents flying with family It was very discriminatory the way we were treated.

A delay of almost 3 hours. It was evident that the staff wanted us to board urgently, to the point of rudeness, to avoid paying compensation

It's not the staff's fault. The cabin crew do their best but the setup in Stansted Airport by Ryanair is poor. The herding of people like cattle is unacceptable before boarding and is something that's in every airport but only in Stansted have I seen the queueing of passengers outside the plane on the tarmac and the crew only turning up with maybe 5 minutes to depart. This is a resource issue . Yes prices are good but seemingly comes with a price of poor treatment of customers. I'll pay more next time

On time arrival but the aircraft had seen better days and needed a deep clean.

It was appalling, full of young people who were drunk and disobeying instructions to sit down. Crew did nothing to enforce. There was a Ryanair pilot sitting in the aisle opposite me who talked through out the safety briefing so loudly I couldn’t hear. Whole thing felt unsafe

Delayed for 2 hours lack of communication no refreshments as promised and the drinks on board were not as ordered and refused to refund

Flight was fine, crew were good, cabin director spoke far too much; disembarking at Dublin Airport and entry into the terminal building was just dreadful, like entering the back door of a neglected factory building. What an awful impression it must give to first time visitors to Ireland.

Straight forward checking as long as you have completed every single detail online, prior to checking day. Efficient boarding, seating is ok for a two hour flight. Fulfilledour travel requirements from Manchester to Marseille.

I couldn’t understand the aircraft tannoy announcements I was in seat 20C - nobody in our row could either. Speakers a bit too quiet plus messages read out too fast. Otherwise excellent flight. (Flight delayed by 50 mins)

I bought my flight, insurance etc early and paid over £200. But had i waited until closer the time the price was much cheaper, i appreciate that it could've been more expensive but it wasn't. A better discount for booking early would be better than your current one

Checking in prior on line and wait time at Gatwick was terrible. I would rate a big fat ZERO.

I checked in to bags, one arrived one was delayed. I did not receive the bag for 4 days - arrived on Tuesday, received bag on Saturday!

It was ok. Our flight was delayed 2 hours, and then again on arrival. The explanation given felt feeble.

The booking agent, cheapflightsfares, messed up, and the information for the seats we paid extra for was not sent to American Airlines. We were separated on the return flight and sent to the lowest economy section. The flight attendant helped arrange seating at the back of the plane to allow my wife and me to sit together.

The staff were fantastic and couldn't have been more accomodating; however, the air-conditioning was broken in our section of the aircraft, leaving us feeling extremely cold and unwell on arrival in Johannesbury. The head sets were also faulty, causing difficulty when listening to announcements and entertainment.

I liked the comfort of the seats, very attentive crew, and the meals were excellent.

We spent twice as long on the runway waiting to take off as we did in the air.

We were kicked off this flight by British Airways due to delays on our connecting flight also operated by British airways and were rebooked on a different carrier which delayed our arrival home by > 26 hours.

Smooth roundtrip to Manchester, UK from SFO. I think BA is fabulous.

Everything about the flight check-in was smooth no line the plane is clean and bathroom
