Very nice flight attendants. Drink service was good. Direct flight left a bit late from Reykjavik, but still arrived earlier than scheduled. Good in-flight entertainment, but didn't remember to bring headphones with me.

Would like some included food service, but I paid a lower price for Economy with that knowledge. I bought a sandwich at the airport which worked out fine.

Late flight. Both flights smelled of latrines. Charge for one checked back one way was 99.00. Flight attendant rude and said no vegetarian meals were available to purchase and I ordered within 10 mins of taking off. First she ignored me, even though she was talking to passenger next to me. I waited and she skipped right over me to next row. I had to press overhead light to get her attention. No veggie wrap available and I was told the vegetarian soup actually had chicken. No food is available otherwise on Iceland air flights. We almost missed our connection and flight crew didn’t even let us off plane before others who didn’t have tight connection. Husband was assigned a seat that didn’t exist on plane. Landing was the worst ever, came in on two wheels—all passengers were groaning. I travel a lot and will never choose Iceland air again.

Flight was delayed 1.5 hours due to an unexplained "maintenance issue." A friend of mine who had paid extra to get an exit row with extra leg room was inexplicably moved to a normal seat, and was only upgraded when she complained. I was moved from a window seat to an exit row without explanation, unfortunately, this was an exit row where a life raft was attached to the door, leaving me even less leg room than a normal seat would have.

Sat in window seat with a huge compartment storage next to me by window - great for easy access to electronics, etc.. Great movie selection. Short and efficient flight and my fears about basic economy ticket were dissipated as I was able to check a bag and get better seat assignment at airport.

Slow service, not served dinner until almost 10pm. Lights were never turned down so difficult to sleep altho I had eye mask and noise cancelling headphones. Seats are not super comfortable but if you bring neck pillow and blanket it’s better.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
