Cons: Very disappointed in my first longhaul flight on Norwegian Air. Check in staff at Boston was snarly, the food was very average, and the leg room in economy was the least I've ever experienced on an international flight. I am 5 foot three and I do not understand how anyone even a few inches taller than me would not be in imminent danger of developing a blood clot. Horrible. This is a Dreamliner? I only had nightmares.

Pros: Flight was delayed for an hour but considering the day before when all flights were cancelled and that whole morning flights were delayed at Reykjavík due to a major storm off the Irish coast the airport check in, security, and boarding went extremely well. Staff on board couldn’t have been more helpful and efficient to get the plane pushed back from the gate and get our flight going.

Cons: The plane’s temperature was a little warm on both flights from New York and Iceland with no means to adjust fans or temperature at your seat like most airlines. The entertainment screen was down for about half of our flight back for both of us to New York but worked fine after.

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.
