Website doesnt work properly, boarding process is a mess, foos options at Reykjavik airport are expensive and not that good, and the in flight announcements were very hard to hear. Also, the pilot made an inexplicably hard landing in Boston on a fairly clear and calm day.

The beet salad and the bouillabaisse were both excellent. The flight attendants were attentive and helpful. Wide selection of entertainment choices.

Our connection from Zurich arrived as boarding had begun in Reykjavik. When we arrived at the gate, it looked like business class had already been called, so there was HUGE mob gathered about the gate including small children. An employee worked her way through the crowd randomly checking passports and marking boarding passes. Eventually we made it onto the shuttle which drove us out to the plane. I wouldn't like to fly Icelandair overnight because I wouldn't be able to sleep at all in the business class seats since they don't recline that much.

Pretty good flight for a good price.

It would be so nice to have tea and/or coffee served before landing. oming in at 5am or 1am North America time is difficult and if you have to travel more that day a cup of coffee or tea sure would help. Serving tea and coffee at ten pm after serving dinner isnt good if you want to sleep..just keep it warm and serve it before we land.

Did not transfer our suitcases on-time to the connecting flight, and we had to go back to the destination airport the next day! Crew during the long flight from LA to London never, not even once, brought beverages or water in between meals! They made sure to do minimum that is necessary! That's a shame BA I flew with United few months back from Washington to Munich and crew were amazing and went above and beyond to serve passengers

No free food, even on a 5 hour flight. Boarding process in Iceland was not very good - no communication, we stood on 1 line for a long time and it didn't move, and they didn't board by row numbers. The good news is that the plane (767) had plenty of overhead storage, despite everyone (it seemed) bringing a carryon.

There was a seven hour delay. No explanation provided. Agents at CMN were rude and unhelpful. In the original flight I had selected an aisle seat but somehow ended up in the middle. My whole rows TVs didn’t work and no one helped us or cared (contrasted to Singapore Airlines which actually cared when a similar issue happened). Customs forms were all in French even though we were flying into JFK. Awful airlines.

About everything else. The boarding process was chaotic, slow, and lacked any sort of communication. No one was queuing properly and the airline staff failed to address this or even announce we were boarding! Had to bus there and this was slow and tedious. Had the same problem with queuing once at the plane. Flight was delayed and this was not mentioned or apologized for at all. The seats were jammed in and uncomfortable. The bathrooms were disgusting and not checked by staff. Landing was barely announced. Just an awful airline all around. Won’t book with them again if I can help it!

The boarding instructions were difficult to hear and the business class passengers were checked into a very small area between the lobby and the jetway where we had to wait to make sure the plane was ready for boarding. I'm 5'2" tall. The seats were roomy and comfortable, but I was unable to reach the footrests and the seat didn't recline very far.

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.
