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

Iceland airlines doesn't provide any meal on flight to and from New York, except water and soda. Airline over charge for checking in luggage. I'm really upset.

Iceland airlines doesn't provide any meal on flight to and from New York, except water and soda. Airline over charge for checking in luggage. I'm really upset. If there is option to use another company, I suggest to other people use them.

I had an exit row and so was Comfortable on the long flight.

The seats on this airline are sooo small, even for a petite person. I felt like the seat tilted forward and I was fighting to stay in it. The lavatory is horribly small, with a wet floor because the sink is so small you can't help but splash the water all over when washing up.

For an economy lite experience, it's by far the best I've had. New planes, clean, great destinations. Very happy to have discovered Iceland Air.

Good. Lacking overhead bin space. No food offered but you can order online or in flight and pay for snacks.

Only serving 2 small coffee in 7.5 hrs flight with very limited choice to order food.

Booked with Kayak… Economy Class it said. I had filtered for 1 checked bag. Get to boarding and it says I have Economy Light w/ no checked bags. $136 each way for baggage now. Do not use smartfares.com. Very misleading and a terrible start to this trip.

Our three ski bags did not arrive and are still not delivered, one full day later. With one ski bag not traceable at all. I would not fly Iceland Air again.
