Friendly flight attendants and reasonable good food. Quick service throughout the trip.

I WAS CANCELLED ! I thought entire flight was canceled but it was still ongoing and I was only canceled as a passenger and one day before my flight with really poor "choice" of next flights that completely ruined my family event. Absolutely disappointed by SAS. Will be avoiding this airline now

The flight was fully booked very hot and there was no room for hand luggage. I was surprised that there was not much leg room for such tall people. My seat mate barely had room for his hand luggage and had to put his feet and knees in front of my seat. Crew was a bit brash considering a full flight and late departure because of it.

Flight crew was very kind and polite. They had to deal with an unnamed issue right beside me, and did so with respect.

The crew were nice and courteous. Exonomy seats were worse than expected. Overhead bin space was non existent thanks to loose enforcement of the carryon size and letting passengers put up their purses jackets and backpacks up there leaving no space for others with a small conforming carry on. Food was not good at all. Perhaps worse chicken I ever had in my life. I had to have them take it after tasting how bad it was. Whoever made that should not be in food making business.

The crew was amazing. Our seats was not very clean and even that was not a full flight but our seats was right beside the WC which did not let us to have a moment of rest.

The stewardess was incredibly rude. The gave you only one drink with dinner.

Crew was unresponsive to request for a soda. Food was horrible and I’d venture to guess many others thought so as well by the amount that they trashed. Made me sick to my stomach and ended up in bed the remainder of the day once we arrived. Screaming child for 3/4 of the almost 8 hour flight. Crew had no headphones whatsoever for free or purchase. Seating way too tight and we upgraded our seats. I do not see us ever flying this airline again.

Nothing special or negative. Pretty typical flight…no freebies in the way of food etcetera, but none were expected.

Boarding and crew were excellent. Seat could have been more comfortable (hard on lower back).

Flight delayed over an hour with plane on runway because of weather in an area of the country we were not in or flying to.

Flight attendant incredibly rude. Stuck her finger in my drink and didn’t even have the courtesy to apologize.

The very best airline service I have experienced. Better than domestic airlines first class and I flew Economy Plus!

The food was horrible. There was no. Wifi, and it was just terrible from bangkok to d. C

Boarding was 2 hours late and then we were delayed another 5 hours on the tarmac. I'm sure the crew were also tired, but some of them were rather snappy. The special dinner I ordered was not served, and they only served a tapas box on takeoff and breakfast before landing. That was disappointing in premium economy. However United was good at rebooking my connecting flight.

It was pretty good, they give a small blanket, neck pillow and earphones. The only bad thing was not big enough leg room for your bag and feet. They gave us a snack, dinner, and breakfast on flight and food was good considering it was on a plane

The crew was great. The food was typical, but decent. Everything else - mediocre to poor. The flight was late arriving - happily for us and our 49 minute connection (what idiot came up with that?)- in another concourse - that concourse changed before we arrived (ticket and app was showing the incorrect gate - when we boarded at the correct gate - known by the airport person pushing my assistance cart). Had I walked and read the screens or United app I would have missed the flight! May other people arrived late to the correct gate, having been victims of a last minute gate change, were also relieved the flight arrived late. The aircraft (Boeing 757) was a sardine-can due to an uncomfortable seat pitch distance. The material or seat was beyond not comfortable, but I'm sure they made a lot of money with that aircraft type. I spent a lot of time standing in the back (in the middle of the night/morning to rest my back). I learned my lesson - any trans-oceanic fight - avoid United or American Airlines - and look for Airbus or Boeing 737, 767, 777. Also, pay for business class or premium coach seating.

We sat on the hot plane for ours with very conflicting messages. Some (most?) of this may be due to the flight control staff, but we were also repeatedly getting "we are leaving"/"we are not" messages. It was very uncomfortable

WiFi didn’t exist , seats were super cramped, lights stayed on near my seat for a long time while others were dimmed, the food/trash/drink cart hit my shoulder at least a couple of times while moving, food options were down to just one option by the time it got to my row, the utensils were garbage (knife bent at a couple of places by the time I was done eating) the spoon was very flimsy plastic

Kayak, the site I went through to book our flight, sent very unclear emails about flight changes. Kayak was incredibly unhelpful in their communications with me about this, promising to work on resolving the issue, and failing to do so. As a result, I needed to get a hotel in Brussels and am now in the process of trying to get reimbursed. On the other hand, the flight personnel in Brussels were very helpful, taking time to look into the issue and determine if they could help. I am very grateful for them and have no problems with the airline. For Kayak, however, I will never use it again and will never recommend it to anyone, and will even discourage people who consider going through that site. My worst experience ever....

The check in crew were so friendly and attentive. Probably the best in my experience and I’ve been flying at least four times a year most of my adult life. Very considerate and I appreciate it.

Absolutely the worst at baggage handling. Our baggage still has not been delivered. They couldn't find it in Dublin then when we got to Edinburgh they said the 2 bags were sitting in Dublin. After spending an hour filling out forms at the counter. We left for our hotel, bags arrived in Edinburgh at 505pm using my satellite tracker. Tried calling the numbers provided, no answer to their 24/7 service. Next morning the bags are still sitting at airport, no movement. Called different number provided by hotel in Sterling, the said it's souly the responsibility of the courier service now and they couldn't help. Completely ruined our travel plans, we must find clothes to purchase today instead of going to the museums we had purchased tickets for. This loss is costing us thousands in already paid hotels and services. No one takes any responsibility. I'll be contacting legal services on our return. We will never forget and I'll be a social advocate to avoid using this service.

I was disappointed with my experience on my Aer Lingus flight from Denver to Dublin. One of the biggest issues for me was the attitude of the cabin crew. They came across as cold, unfriendly, and unapproachable. There was very little warmth or friendliness, and I rarely saw anyone smile. I did not feel that the crew made passengers feel welcomed or cared for, which makes a significant difference on a long international flight. The cabin was also extremely cold and uncomfortable. What made this more frustrating was that we were instructed to put everything, including our blankets, underneath the seats at certain times rather than being allowed to keep ourselves covered. Considering how cold the cabin was, this was particularly uncomfortable. I also did not appreciate the tone used when giving some of these instructions. At times, the communication came across as unnecessarily loud and abrupt rather than polite and courteous. I understand that cabin crew have important safety responsibilities and passengers need to follow instructions, but those instructions can still be delivered in a professional, respectful, and friendly manner. Unfortunately, the lack of warmth and hospitality from the crew was the most disappointing part of my Aer Lingus experience.

Cabin crew was one of the worst in memory. Poor in delivering service - in some cases skipping it altogether. Someone in baggage handling managed to steal my electronic bag tracker from Apple.

I buy ticket from you and when I go to the airport aer Lingus they tell me you need travel visa for Ireland for one hour travel so when I buy tickets there no requirement I need transit, visa or not so when I try to cancel my ticket or change my ticket, you guys say there is no refund so you u guys take all my money which is very disappointed

The aircraft was clean and relatively comfortable- for an aircraft seat. The entertainment was good. The food was terrible, especially the “breakfast “ which was a cereal bar, and just not good. The crew were amazing, professional and no complaints there. The food was so bad, I know for my return, it will be inedible.

Flight crew was superb. Meal was one of the meals at altitude I’ve had

Couldn’t check In online, message was couldn’t check in until Sunday morning though plane left Saturday night. Checked in okay at airport but caused slot if stress.

The only problem was there are games on the entertaiment system. The guy behind me played poker the entire time and poking the back of my seat. I hope they remove these.

Flight was ontime, clean, staff was friendly - there was turbulence but can’t avoid that (it’s a flight 😉)! The staff were attentive but would be nice if Aerlingus didn’t charge for coffee ☺️ but overall I enjoyed my flight experience and will travel with them again (Ireland’s Four star airline

Luggage delayed and delivers 24 hours later … broken. No resolution… no response. We don’t have a suitcase for the rest of our 2 week trip

It was great like always had all my 3 luggage and I got to my destination safely

Everything was better but france airlines more better than them

Spacious and clean aircraft. Good food. Economy will always be squeezed but thankfully I had an aisle seat for stretching exercises. Good selection of movies, particularly Spike Lee joint.

Unfriendly, 8 hours delayed, no lounge access even flying business. Don’t fly Brussels

On board service was decent. I like the legroom at UA that seems to be more than in other airlines

The flight went well, only during the flight from Brussels to Vilnius I would have liked if they had at least given us plain water to drink.

The crew and the flight were excellent, the food might be better!

This was absolutely one of the worst experiences of my life. I came to Europe for a 2 week trip and the airline was probably the most disorganized airline I’ve ever seen in my life. They lost my luggage. I had tracking on it for just such an occasion and told them EXACTLY where it was in the terminal and they somehow failed to get it out on the flight that night, since we were leaving for Switzerland the next day there was no way they would get it to our hotel in time. Seriously, take another airline at any cost. It’s not worth whatever you pay…you’ll end up paying a lot more in the end. My medication is in the bag and I can’t get to it and don’t know how I will get it.

I felt the overall quality of the plane and food service was less than that of their partner airlines, United. An example was wine was served in paper cups in premium economy class. There was no real silverware, napkins or a welcome kit other than a pillow and blanket.

Movies were old and third rate. Very poor on a seven hour flight. Food was OK but not business class caliber

Although the flight from JFK to Keflavik is not inexpensive, Iceland Air offers nothing but water, no soft drinks, to passengers without a charge. The seats are uncomfortable, there is no leg room, and there was no available internet to purchase.

Was hard to sleep, but other then that everything was good.

We got to the runway and had to go back to terminal to have plane worked on, which is fine, but the 40 minute connecting flight was already gone because of this delay and had to wait 5 hours to get on a different flight and only got a meal voucher which I didn’t see the email until after I had already ordered and paid for food. I feel I should be compensated.

Handling our luggage was the biggest issue - they lost it and we got it almost 3 days later. Really threw off the beginning of our trip and we really had to change our itinerary accordingly.

The flight was delayed and as a consequence we missed our connecting flight. Were stuck for another 6h in Reykyavik. Appreciated that we got a generous food voucher at least. Would have liked to see more information upon arrival including a person waiting for connecting flight travellers and informing already that we will not catch the flight and directing us to the office dealing with the matter; unfortunately that didnt happen and we hence first needed to find out whether flight had indeed left already and then locate the adequate office to help us with booking us on the next connecting flight. Also my suitcase broke and it is not clear whether it is happened on the leg with Iceland Air from DC to Reykyavik or on the leg with Lufthansa from Reykyavik to Frankfurt. Finally, understood that it is a low cost company but at least provision of earplugs for free would have been nice, instead of making them buy.

Had a screaming child next to us. Not the airline’s fault but still annoying.

Seats are way too much now with these new airplanes especially long flights like we had. I was 7 month pregnant and in a lot of discomfort due to small seats.

My biggest problem was the flight from KEF to DUB was delayed, which caused me to miss my connecting flight in DUB and we were forced into an unplanned 10-hour layover in DUB. Crew and boarding staff were all very friendly but this was a real inconvenience and especially uncomfortable for my disabled wife.

The seat size was more like a domestic than an international flight. In fact, i would compare the ammenities, quality and service to a short hall ryan air flight, which was unexpected for an international flight. The plane was extremely hot so sleeping was difficult. My biggest complaint was that they are very strict on carry on luggage only allowing it to weigh 10kg/22lb. I try to limit myself to a carryon so i don't have to mess with bagage claim, but the wieght restriction made it impossible. I have never had a carry on weight restriction (at least enforced) on an international flight. Will not be including them in future searches.
