Got stuck on runway in Reykjavik because of rain storm... For 5 hours, on arrival at 10pm, until 3am. Weren't allowed to order food, or alcohol. After several hours they offered soda and chips. But nothing else to compensate, no flight credit, etc. Friendly crew but very bare bones experience... Bit of a nightmare.

The personnel were most helpful, pleasant, and reassuring when I discovered I had left something on the plane. It was found and returned to me quite promptly and my continued flight was rebooked with the minimum of fuss (and embarrassment). Everyone was wonderful.

I am not a seasoned traveller. Checking for a small item (such as a passport) in the overhead compartment was not possible.

The seats were roomy and comfy and I was glad I didn’t have to pay extra for a seat like other airlines.

Boarding was very confusing and the customers reacted by plowing Willynilly down the ramp nano seconds after the physically challenged were wheeled on to the plane ignoring the airline staff at the gate. I went with the flow praying I would not get arrested. We boarded a total of 40min late . Second if I am paying for my baggage I should not have to wait 30-40 min for them to come out at baggage claim.

Iceland air have a good product. They fly 757 and 767s that are clean and well maintained. Staff is very helpful, I changed over a flight during the layover in KEF and it was flawless, I got my checked bag as promised in CPH which was quite well done. So, they went out of their way to accommodate me. KEF does great with passport control and the lounge there is very nice.

KEF is a busy airport, always at capacity for travelers. Depending on the season it is hard to find a seat at the airport let alone the gate. During summer it is hard to even walk thru the airport. Depending on your abilities, give yourself time to get to the gate.

The check-in staff were very friendly and helpful.

I already knew I was going to pay $200 to ship my boards back home (I wonder if golf clubs which are roughly the same size cost as much,) but when pre-purchasing through the app for an "oversized" bag you have to put a "one" in the checked bag and a "one" in the oversized bag even though they're the same bag, but then they charge you for two, and when you tell the check-in person that you only have one bag of course they can't issue a refund. No, they tell you that you get to call customer service when you return home.

When I got to Phl I missed my connection to London. No one seemed to care that I needed to be in England by the 18th. They kept retorting me to arrive in England on the 19th. I told them multiple times Id be flexible and go to any city in the UK just for them to get me there on the 18th. The First person I talked to said it was impossible. So I called again and talked to another person and all of a sudden it was possible. The worst part was they sent me to Boston after that I didn't get to Boston until 1:50 am and they did not compensate with hotel or anything while my flight to London was not until 8:00 am the next morning. So I spent the night in the airport. Oh and then when I finally got to London, my bag is lost and they told me I'd have it by tomorrow and I still do not have my bag and have called and they said they can't tell me anything.

Legroom is above average, but at expense of seat comfort. Food is good but expensive. Crews were attentious and courteous, but not a strong differential from other airlines. Entertainment was good and easy to access.

Boarding in all of our 4 flights was chaotic and a combination of lack of organization from Icelandair and discipline from passengers. Space for boarding is scarce and confined. And when they call half of all passengers of a full 757 or 767 to board at the same time... the law of the jungle is stablished. Even with just a little more effort and organization from the airline it would be possible to make this a better experience for all passengers. Be aware of what you are told when you buy your tickets. They sold economy tickets to us and then charged a lot for bags telling us our tickets were economy light, even with their own receipts or tickets not mentioning anything about light on them.

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.
