Pros: Good price point. Very nice and efficient crew, greeted at boarding with pillow, blanket and water bottle. Entertainment with free movies and very nice travel info-logues on Iceland. Airline offers up to 7 day Iceland stay-overs at no extra cost. Nice legroom on the 767, and I'm 6'5".

Cons: The small personal pizzas were so-so, sandwich was pretty good. Alcoholic drinks were somewhat expensive. Reykjavik airport deplaning was via outside stairs to a bus in mild rain, but that's probably not the airline's fault.

Cons: I went to the restroom in the back, and one of the flight attendants was sitting in her jump seat, with head phone on and appeared to be sleeping or resting with eyes closed. Her sprawling legs were blocking the aisle, therefore I could not get to the restroom on the other aisle that was the only one open at that time This is unacceptable. Also PA is way too loud.

Pros: We were lucky that the flight was not full, more space and comfort. Our special meals ordered in advance were provided how ever a little limited Flight was generally smooth and we arrived earlier than scheduled even though we have left later than scheduled. Great service. New, Clean and comfortable aircraft The process while in transit at Lomé was fast and simple.

Cons: The fasten seatbelt was constantantly on (not only while in turbulence) Though we had two full rows available for us, the seat handles could not be lifted; hence the full row could not be utilized... No entertainment at all. This can be advised ahead for you to come with adequate tablet.

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.
