Everything went smoothly enough.

There is no real place for passengers to sit near the gate in Keflavik airport while waiting to board. At least not enough seats to accommodate a huge jet full of people. So this results in giant, awkward lines of people. But once the boarding process started, it went fairly quickly.

Extremely polite and professional staff who spoke English perfectly. Very impressive. And the flights were all on time, which was very much appreciated.

Wish we could have had access to movies. Even if we had to pay to watch them. Overseas flights are too long for no in flight entertainment.

Not sure how to feel about waiting 40 mins for another flight. Good for those passengers but what about my plans (and 100 other people on the plane)?

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.

More questions or if you have a bad price to report to us
Please send us an email and someone from our team will get back to you promptly.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days. Fares are subject to change and may not be available on all flights or dates of travel. Some carriers charge additional fees for extra checked bags. Please check the carriers' sites.
