First time traveling with WOW and it was okay. Price was decent, a little better than Spirit, but the same with paying additional for everything so it's not really saving. Overall, great flight the pilots did a great job getting me to my destination (there and back) safely and with time to spare.

For a 9 hour flight they should accommodate their passengers with free beverages at least. The seats were very uncomfortable. Flight attendance were polite but very hard to get a hold of, they talk too much among each other, like HELLO you're working get it together! My flight was delay returning back to my original destination and no communication was received until a staff member showed up almost 2 hours late.

It's OK to ask to pay for everything as long as the flight is on time. But no matter what was the flight - Boston to Iceland, Iceland to Paris, Paris to Iceland and Iceland back to Boston - flights were late - almost missing the connection in Iceland back to Boston. And the fact that you have to take a bus at the airport in Iceland for your connection and wait 20 minutes in the bus is just not acceptable...

Planes are comfortable and new and the staff are nice. The price is right. When we missed our connecting flight, they did provide hotel accommodations and meal vouchers.

Every single leg of my journey was delayed. We missed our connecting flight and got trapped in Iceland for a day. The plane didn't show up for 45 minutes and then we had to sit on the runway due to high winds. The staff didn't know anything or wouldn't tell us anything when all the travelers started to get nervous about missing their flights. Poor communication.

Flight way delayed 3 hours. Staff gave no information and wouldn't help rebook us onto other flights. They gave us food vouchers 2 minutes before we finally boarded, so we couldn't use them. The food on the plane had spoiled so we were all starving on the flight, and we all missed our connections. Horrible experience and wouldn't fly with KLM again.

Excellent leg room. Comfy seat

Seat couldn't recline back. Was a little uncomfortable for a long flight. Chair had crumbs on it before I sat down-it was easily wiped away meaning no one had cleaned the chairs or looked at them beforehand. Absolutely freezing. Wearing long socks and boots and my feet still felt frozen by the end.

Same previous comments. They left us leaving the gate and entering the bus to get to the plane, but we had to wait first at least 20 minutes in the bus leaving the gate and another 5 to 10 minutes before entering the plane. That's just not acceptable in 2017...

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,
please send us an and someone from our team will get back to you promptly.
