Food was terrible. Crew was kind but skipped over my row for providing sandwiches and beverages.

Food was terrible. Crew was kind but skipped over my row for providing sandwiches and beverages.

I learned that seating towards the end of plane that a line forms for the restroom and people use your chair as a hand railing, bumping your seat consistently. I was seated in the aisle. I think that next time if I am towards the back row I would want to sit in the middle or window seat.

The attendant were friendly. I suggest you have a medical attendant on board every flight so that in case someone is sick , he/she will help them.

Awful. There was a minor problem with a fridge and they had us 2 hours in the runway before take off. The paper work alone took them half hour. There was no attemp to make up time up while in teansit and when we arrived, they had us another half hour in the plane because of traffic. I, and a bunch of people, lost their onnection flights for 5 to 10 minutes. Not even the attemp to wait given thar all delays, but the taxing, were United's fault. Then another 45 mins to get an agent and no flight alternatives for 2 days. Im am very disapointed with this "premium carrier".

The design of the light switch on the arm rest is ridiculous.

We were delayed in Toronto on the tarmac for THREE hours with no clear indication as to why except that it was not a safety hazard. Pilot did apologize more than once but even he was unable to explain why exactly we were delayed. I overheard the stewards saying that the captain was very frustrated with the situation as well because he was not able to explain why except it had something to do with water supply or system on the aircraft and now we needed to wait for an engineer to approve the aircraft for flight. It was very frustrating and distressing as a passenger and we should have been given complimentary meals at the very least.

We paid extra for the seats with extra leg room. But we were not allocated the seats with extra leg room nor refunded the money we paid for the seats.

Very good - being handicap it was very hard for me in a center aisle bulkhead seat that Zi was assigned think it was 29-G as I had a hard time opening the entertainment screen and tray table. 30-G would have maid it easier. I was assign 29-G as it was the only handicap seat without being charged even though I was handicap (disability)

The agents was very rude and they charged me $50 for a carry-on bag saying that it was too big and then I saw someone going on a plane with the same size bag as me

Very punctual. Comfortable plane and great entertainment options. The staff was very nice.

Boarded with no problems. Sat on the tarmac for an hour before taking off. We were the last ones on our connecting flight. Didn't think we were going to make it. Our flight to Iceland was similarly delayed. When we've flown other airlines, pilots have tried to make up time while in the air. This doesn't seem to be something that Icelandair does. We made all of our flights, but it was stressful and we didn't think it was going to happen based on the time we arrived.

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.

Great experience on Icelandair flight from Newark to Amsterdam by way of Reykjavík. Courteous and professional staff. Food was solid. Service - outstanding. Cabin was a little warm.

Good service. No complementary food for international flight. WiFi kinda pricey. Got the job done for the right price.

The plane was very small and the aisle was so narrow that every time someone walked by they rubbed against me, so it was very uncomfortable.

Everything was good. Only issue comes from being vegan and flying. The food options are super limited.

Overall good for an economy fare. IMO the movie selection could be improved. Great that you can now connect bluetooth headphones to the entertainment system.

For a four hour flight, I was disappointed that everything was for purchase except for coffee, tea, or water. The disembarking in Iceland was so inefficient and time-consuming. We landed and stopped in the middle of the tarmac, had to disembark in the rain, and then squeeze into a bus which took us to the airport. Crazy! How does that work in winter?

Paid for a Premium seat...minimal recline, no footrest. Maybe slightly wider than a cheap economy seat. Zero chance of getting any rest on this plane

Seats in premier saga class were narrow and hard. Very uncomfortable for a 5-hour flight.
