Probably not much to expect from a European domestic flight but it helps if they check the airplane for safe travel before boarding people. We had to stay on the tarmac and go back to gate for some sensor malfunction and refueling for two hours.

Probably not much to expect from a European domestic flight but it helps if they check the airplane for safe travel before boarding people. We had to stay on the tarmac and go back to gate for some sensor malfunction and refueling for two hours.

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 very helpful and friendly. Food was good. The only issue was the legroom -- not great. The seat in front is also too close to see the entertainment screen properly.

Everything was perfect. I would’ve liked better selections for entertainment, but I slept most of the time, so it wasn’t really an issue.

No crying babies the whole flight would be nice. Impossible to sleep. No free snacks , only the main meal

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.

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.

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

Staff didn't seem confident about the ingredients in my lactose intolerance meal

the seat has a problem. the back had a hole.

My flight was delayed so bad i missed u it so i just said never mind

Delayed 2 hours while stuck on the aircraft. If the luggage was properly loaded the first time we probably wouldn’t have been delayed at all

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.

Hard to figure out how to put back the seat, how to get the entertainment, how to upload passport docs. Also, a warning in the airport that food was all for purchase would have been helpful.

Horrible. My dad was recently hospitalized and diagnosed with lymphoma and Icelandair refused to refund flight even though I had a letter from his physician.

The WiFi wasn’t working, so no one could watch any entertainment for 5 hours. The plane also was delayed and did not leave, nor did the staff prioritize those with connecting flights to de-board first. Everyone with a connecting flight to Munich missed their flight by 5 minutes. Then the next flight to Munich was 14 hours later. The airport could not compensate us because the closest hotel was about 2 hours away. This did not seem like the truth. I was not pleased with this traveling experience.

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.

Staff in flight and at the airport were very helpful. A short time between flights made it stressful to get to the connecting flight and we probably would not have made it without the staff’s help.

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!

Our flight was delayed for over an hour due to weather, and it had already been a long travel day. However, the crew was calm and compassionate, listening to every complaint with genuine concern. They got us home safely without incident, in spite of all of the obstacles. I’m grateful.

Bad! Disaster!! The LH419 was cancelled after 4 hrs on board with no AC and no toilets

We had almost a 6 hr delay, primarily due to weather, the e problem was that they communicated this delay and its length very poorly. The boarding was chaotic - even though they had hours to figure it out! The plane was an old 747 whose touch screens barely worked and there was a faulty USB port under my seat rest (something that wasn't labeled as being there) They organized my delayed luggage well. And I could get updates on the Lufthansa website. My shirt connecting flight charged for everything except water. Coffee was over 3€

It was freezing. I asked crew member for a blanket and was told it might be in front of plane but I never got one. I turned off all the vents but still froze.
