Good 6.3

Pros: The crew was nice and the movie selection was decent. Food was ok. As good as it can be when you pay $2,500 for a flight ticket knowing that they are not really there to offer you a service, they are there to make their own money knowing that as a traveler you really have no options other than an airplane if you want to go across the ocean.

Cons: The difference here is that in a 9 hour flight you want to keep hydrated. Crew seemed lazy...they would not bring water to travelers very often...and when I called a flight attendant with the button call and politely asked if I could have some water, she seemed pretty annoyed and told me I can just stand up and go take my water in the back where they store food. NOT A GOOD SERVICE FOR $2,500!!!! It’s outrageous!! Seats become smaller and smaller...and you keep asking about my experience...$2,500 to travel seating in a miniature seat with no leg room is a bit much...and I know no flight company cares about this...we have no choice...either take that or don’t travel, right?

Pros: It was cheap & they get there fast.

Cons: Where do I begin? First they gave me a dirty blanket to use. Next they do not give you any snacks. That might sound trivial but on an 8 hour flight every other airline I’ve ever flown with has offered their passengers SOMETHING. You do have the option of purchasing food but it’s expensive & it wouldn’t feed a preschooler. The crew...honestly they’re just not pleasant to talk to. I put on my call light to ask about purchasing (which means I’m spending money) ear buds & she made me wait another hour & a half. Not one single passenger I spoke to had anything nice to say about Iceland Air.

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

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 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.

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.
