Staff at the check in counter were unfriendly, we stood in line to ask a couple questions and the 2 women working behind the counter never addressed us and just carried on their own conversation. Our experience at IAD was not any better. Overall really not a fan of Iceland Air.

Very kind & courteous staff. Plane was new and very clean, with awesome touch-screens in the back of every seat. The movie and music selection was also excellent. Our flight was only about half-full, so people were able to stretch out in rows of seats.

It would have been nice if IcelandAir provided a meal for this transatlantic flight (or even a little bag of pretzels!), but considering the steal we got for this flight, it wasn't a huge deal. IcelandAir was generally fine. The customs process in Cleveland was atrocious. We had to go through TSA security again even though this was our final destination. Duty free items were not allowed through this security check; fortunately, one of the agents let my husband place our larger-than-3-oz liquids in a bag that was sent to the baggage claim. Especially for travelers like us who had been up for 20+ hours and flown across oceans, this was a source of significant stress and was generally terrible.

Hidden charges!!!! I was not advised until I checked in that I had to pay extra $90 for my ONE checked bag. Then, I was told that if I had paid in advance that I could have saved -20%. Then I was told that I would have to pay again on the return. And I could not pay at that time to get any discount on the return baggage charge. So the Kayak ‘discount fare’ wasNO DISCOUNT, only additional restrictions, like inability to select an isle seat for my long legs.

I am not sure why this happened, but our daughter, travelling away from home for the first time, was targeted at every step of her journey. From the terminal in DCA to Cincinnati, to CDG. Delta/Air France clearly singled her out. i am outraged! I have traveled many, many times and have sent hundreds of students on nearly the same trip -- and none have had as rough a time as she had. They will be hearing from me.

Our total flight time was about 17 hours - MAD- AMS-LAX. My husband and I both have an internationally approved carry on luggages with us. When we checked in - they asked us to both check in our carry on luggage. The reason why is because they said they don’t think they have enough space for our carry ons. I told the crew member checking us in that other people that was checking in with the same hand carry size luggage with us had no problems taking it with them. For being about to be on a 17 HOUR FLIGHT we should be ALLOWED to have our carry ons with us! We take carry ons for that reason! I had to argue and prove my case to the crew member to atleast keep 1 carry on with us. I thought that was an UNACCEPTABLE reason for us to check in a carry on luggage when we had a 17 hour travel time ahead of us. Not a happy costumer here.

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.
