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.

Pros: Cancelled 30 minute flight up to Vancouver which reaulted in missed flight to Australia. Air Canada the refused to put us on another flight. Went round and round for 5 hours with Air Canada until they finally put us on 3 separate flights getting to our deatination almost 48 hours late.Horrible

Cons: Notify passengers if short flight has more than 20% chance of being cancelled. We could have easily driven to Vancouver. If flight is cancelled, then own up to it and put people on next flight.

Pros: The crew is excellent. Very friendly, professional, and helpful. Both on board and at the desk inside the airport. They listen to your needs and respond the best they can. Seats are comfortable enough for Economy. Good selection of movies to watch. The flight was on time and arrived even a little earlier than expected.

Cons: The food was filling, but not particularly tasty. For those seated toward the back, there was no choice. Although maybe there was no choice to begin with. Normally, on international flights, for the first (bigger) meal at least, you are given two choices, such as meat or vegetarian, beef or chicken. The food itself wasn't great. The salad was below average on both flight, from and to Chicago. So was the desert. Drinks are offered once with each meal in very small glasses. Although there is a bottle of water from the start.

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

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 rentals 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.
