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.

Excellent service, and came on time! Thank you for your dinner that was chicken with salat/, and 🍰 it was good quality food , the breakfast was very good with good cheese , butter,etc and the tea was very good quality. The space where I was seat was nice so I could stretch my legs. I dit not have the bread as I am in a keto died. Have great time everyone in Scandinavia airline.

You cancelled my flight and didn't arrange another. Sent no info except YOUR FLIGHT HAS BEEN CANCELLED. HERES WHAT TO DO NEXT. and the rest of the email was blank???

The first flight was delayed. We missed the second flight, which was rebooked 9 hours later. We missed all our arrangements for the first day of vacation.

Mediocre. Maybe due to Economy light. Staff was great. Space shrunk, not for me, and definitely not for Vikings. Food was decent. Assistance lagging. There was a possibility to upgrade to Premium economy, however my bid was immediately classified as low and not even considered (though well over minimum bid). Thus I was no bleeding dry.

Basic flight. Great for something under two hours. Seats were a bit dated and uncomfortable

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

Excellent crew members, but my seat and food wasn’t the best

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.

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

1. Everything was satisfactory concerning the flight. 2. Can't think of what could be better right now.

Onboard staff was courteous, helpful, responsive and friendly. The boarding process was disorganized, poorly communicated, and disheveled. Gate agents were yelling instead of using the PA system, didn’t communicate the timing delay of our flight, and created an atmosphere of chaos rather than order and communication. As far as I know, there was no reason for their. I would hate to see how it operated under extreme conditions. I’ve never seen United Airlines operations in such a state.

The flight did not have its customary snacks during the flight. Apparently they were never loaded on the plane.

Worst service- attendants dont want to help and sat us in front of bathroom

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

Staff could’ve been a little more cordial. The men were much more friendlier than the women. My daughter and I also missed the 2nd to last meal as we were sleeping but that is on us.

For my wife to be seated with our two children they put them in the last row on the plane where the seats don’t recline very much. The seats in front of them reclined fully which is basically in the lap of the last row which made it difficult to eat, move or watch the entertainment provided.

Like: departed and arrived on time. Unlike: Food options for purchase allways bad, 1 of 2 of the crew members not very friendly at all. Seats and leg room aweful. At this point I am thinking on switching to AA.

Over 5 hour delay with minimal updates or ability to standby for alternative flights. During boarding and 1 hr+ wait for takeoff, seats were drenched w water from air conditioning condensation and always leftover crumbs on carpet and seats

Due to late arrival flight we missed the connection. There's no way possible we could have made it through customs and made the flight to Prague given the time allowed. Even if there was no delay from MIA to FRA I question if we would have made the PRA flight.

Food was mediocre, but as expected in economy class on an airline. Wrap was ice cold , my son’s served by a steward on the next aisle was warm . As expected, but at least heat the food up a bit. No frills, but it’s economy. Excellent free WiFi was a bonus

I flew Aer Lingus Business class for the first time. Having flown economy a few times, I was familiar with the airline, and happy enough with economy. I’ve certainly been in nicer economy airlines before, but Aer Lingus is usually very reasonable, and I find the staff to be kind and have an Irish sense of humor and accommodation. The business experience was good, in that you got superior service to the back, lay down seats, better food and drinks, and more attentive service. However, the plane was a bit older, the WiFi was slow(not Starlink) and the pods were too close to one another for privacy, or function. When the Oder lady to the left of me fell asleep(fully reclined) there was no way for me to escape without having to wake her and put her seat all the way up. That lead to me being stuck with luggage I couldn’t put away in a cramped(for business) space, and no way to use the restroom for almost the whole 8 1/2 hour trip. I ended up trying to sleep with a large backpack blocking my feet. The food was good for plane food, but not great. The drinks were great, shame I couldn’t have had more, but I’d have peed myself. I love a window, but next time maybe an isle seat. Overall, the experience was good, not great, but an expensive good experience during which I got zero sleep. I’d do it again, but it’d have to be a deal.

The direct flight was a superb idea; please continue. The seats were less than comfortable for such a long flight.

We missed that flight, and I am hoping that we will got the refund. It was very confusing to figure out about Aer Lingus operated by American Airlines. Then we bought another more expensive ticket to travel.

The check in and boarding process was smooth, and the flight was fine.

The free WiFi was great so I could stream movies during the flight. I would like to have movies available instead of on my device. Thanks!

We had a wonderful experience with Aer Lingus. The seats were too close for the long trip. The crew was absolutely perfect. They were so caring and thoughtful! My husband did not have a good experience with Air Lingus on the phone when trying to take care of getting better seating because he is disabled and needed a wheelchair prior to the day of our flight! Mariam R. in Boston was so helpful with seating and getting help for my husband. Filip Pytka who works for OCS was extremely helpful! He made sure that we had the lift because my husband could not climb the stairs to get onto the airplane. He took us from the gate all the way down to where we needed to be.

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.

I DO NOT recommend Iceland air...missed connecting flight.....paid for isle seat upgrade for health reasons...had to do that over....baggage left in the rain so clothes got soaked other items ruined....called customer * dont care* service

The ticket was reserved in my name but not paid for by underpricer. Alaska airlines was unable to issue my ticket (could not connect the ticket with the PNR) due to an error with underpricer and I spent the better part of 2 hours at the ticket counter trying to rectify.

Damage May baggage and I report the airport agant and they see it

Crew was very friendly. Need lay flat beds! More snacks

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.

Very efficient and excellent service. Nice amenities and beautiful plane. Elevated meals. Boarding could have been more organized. We missed our connecting flight due to EU entry but Lufthansa was extremely quick to rebook us.

Missed it by a couple minutes and couldn’t find an alternative flight so had to spend the night in DC and after much shuffling from 1 airline to another managed to get a United to Frankfurt.

There were only 2 toilets and one of them did not work in business class. We are not allowed to cross classes so had to wait in line to use the toilets!! The entertainment touch display was finicky and did not work all the time.

The flight and crew were good. The customer experience on the ground could have been better. We had to reschedule our flight because of a delay on the previous flight. The attendants working the desk in Washington DC were not helpful. They told us to scan a QR code and that would get us rebooked. Why couldn't two people standing at their computers do this? We had to chat with someone to get everything figured out. It was extremely confusing.

good entertainment package but rather small seats for business class

The male attendant has zero personality. It seemed like he was over worked or hated his job, not once did he smile or made any contact with the people on the plane. Strictly business and call it a day!

Lufthansa staff was fantastic, but the airport was a mess. I was at this airport in the past and I have never experienced any problem, but this time it was nutty because of soccer tournament: UEFA 2024 championship

What food? What entertainment? The questionnaire does not make sense.

The transatlantic leg was on Discover Airlines. I’m 6’2” and the extra leg room seat was acceptable, the seat it self was moderately comfortable (slightly softer than a church pew). The food was a standard economy fare. Frankfurt to Prague leg was on Lufthansa the business class was as advertised 10 across the board.

It was only an hour flight, but at that, it was still late
