OK 5.3

Pros: Did not realize I purchased a “no checked bag” fare - and the $60 each way charge really pissed me off, along with the &48 charge to guarantee a window seat again, each way. The site was misleading, and I resent being peneluzed for trying to be efficient. A two week work trip needs to include a checked bag.

Cons: For a new plane, seats are very cramped. If you drop an earpiece on the floor, you pull a muscle to retrieve it / or make. Everyone in your row stand up. Decent movies mean a box under the seat cuts into legroom. A cramped, miserable 7 hours for this 6’0 tall American. Staff was as helpful as they could be, but my knees still hurt.

Excellent 8.0

Pros: The plane and it’s crew were fantastic! The crew was totally customer oriented and provided great service for the entire flight.

Cons: It does no good to upgrade to Saga Class when you consider loading at Keflavik. A mob is herded on to a crowded bus and you wait at plane side with little room to move around. There is no priority boarding and the entire procedure might be acceptable in the Third World but certainly not in a country that has so much going for it.

Boarding was ridiculous. we were supposed to form a line and wait. Would have been a lot better if they boarded by seat numbers. Also they made me check in my fairly small and light carry on bag resulting in its contents arriving broken!

And they tell you need to download the app after you exit the airport area and lose WiFi and coming international couldn’t go and download before flight. United was a huge disappointment.

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.
