There was no lounge at Boston for us to use. Typically flying first class overseas comes with lounge privileges. The seats did not recline even a little. My headset only worked on one side. I felt like I was flying on Ryan Air, not Icelandic Air.

There was no lounge at Boston for us to use. Typically flying first class overseas comes with lounge privileges. The seats did not recline even a little. My headset only worked on one side. I felt like I was flying on Ryan Air, not Icelandic Air.

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.

Still one of my favorite airlines, but the entertainment options were a bit lacking. It didn't help that my screen didn't work on one of the legs of the trip.

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?
