Cons: After paying for 2 seats next to each other, Iceland Air decided to change the aircraft and reboked us on regular seats. I am 6ft6 with bad back therefore booked the extra legroom seats and want to have my wife next to me to assist me with putting the carry-on lugage up in the spaces above. We ended up sitting 3 seats apart, I was in the extra legroom seat but in a middle seat,so I could not put my feet in the isle to prevent leg cramps. When we boarded the flight from Reykjavik to Boston I notified the stewardess and she assured she would help, but I never saw her again and no one came to our help. Also when we entered the REK airport after flying from Amsterdam we were not notified to keep our passport on us, as we needed to go tru another checkpoint. My wife had our pasports and went to check some shops, while I was reading a newspaper. After noticing that I could not go to the boarding area for our next flight, I was able to locate my wife and we barely made it to the gate in time.

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

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 prices, so it’s not possible for us to guarantee what other companies are selling.

We aggregate tons 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 don't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car hires 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.
