I originally booked a straight flight from KEF to SFO 2 months in advance and all of a sudden WOW sent me an email saying that they changed my flight to a different one with 6 hour lay-over in LAX due to overbooking. And the email notice was sent < 24 hours before the actual departure. So if I didn’t check in online, I would never find out before coming to the airport. When called to inquire more info and request to change to a different flight that would work better for my schedule than the one WOW automatically decided to switch me to, the representative was not very helpful and giving push back. I had to talk to a manager... Long story short, the flight itself, the seats, and attendant crew were all fine, but the booking/scheduling is a bit of uncertainty (like they can change flight on you whenever and to whatever they want).

They provided a pillow and blanket which was very nice, and the crew were helpful in finding space for items during take-off and landing. The boarding and exiting were fairly quick.

Everything on board costs extra, including basic drinks and snacks, but that's to be expected on cheaper flights. I assumed that the inflight movies cost money as well, although I didn't watch any because I didn't have headphones.

Disorganized and horribly untransparent. The flight left the airport more than an hour after we were supposed to, but we were given no updates. Instead, we stood in a hot tunnel for an hour, then in a hot shuttle, and then sat on the plane.

We were not told we would have to land the air craft in Canada to refuel until we were taking off. This caused us to miss our connecting flight in Iceland and turned what should have been a 1 hour layover into a 24+ hour nightmare. Now, our return flight has been indefinitely delayed and we do not know when we can get home or how.

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.

If you have more questions or if you have a bad price to report to us,
