Absolutely chaos boarding, seats way to close together in both width and length. They had open seats with more room, told me I couldn’t move seats but let others. Each leg of the flight the pilots landed like the plane fell out of the sky! The crew was yet again nowhere to be found during the flight. They do offer food for sale during the flight but it’s at outrageous Icelandic prices!! Never again!!!

The good InterCity Hotel to wait out our cancellation.

Any airline might need to cancel a flight, but WOW Air needs to work at its communication.Was it weather in Chicago (the forecast was fine), Reykavik (but another flight headed out the same time), or were we lied to? We learned our flight was cancelled at the gate. Other passengers received phone messages, we did not. There was nothing on the monitors in the airport to say the flight was cancelled. Cannot WOW and the airport ensure this is communicated in multiple ways? We were grateful WOW put us up in a nice hotel for two days, but did it have to be two days? We re-booked and got a confirming email, but with no evidence of our reservation on the app or the website, we headed to the airport not knowing whether we had a seat or not. Hope this helps to prevent customers turning away from WOW because the concept of WOW is a good one.

The cabin crew, their uniforms, the pink lights, the menu for souvenirs.

Lack of communication, fees are very expensive for luggage. I flew Toronto to Iceland and Iceland to London. In Toronto the crew arrived late and had people who checked in online come and show their iD documents. People were confused and lining up for regular boarding so half way through they just started boarding. It was ridiculous.

Our first flight was delayed so they held the aircraft for us! Crew were accommodating and helpful!

There was no in flight food, and due to the fact that our initial flight was late it meant we had no chance to purchase food at the airport. We were informed by email, but only the same morning, by which time we were already in the air!

Staff were very nice on the flight. Price of ticket was great if you're able to travel light & bring a small personal item only (otherwise you are charged for baggage).

Your flight is only economical if you don't need to bring a carry-on or check a bag. Also if you bring your own snacks/light meal as everything else is an added cost. Water isn't even provided. Seats are ok, could be a bit more comfortable.

Tried to reschedule flight just a few days later because of a friend's wedding. It would have cost more in fees to reschedule the flight than it cost in the first place, and THEN I would have had to pay for an entirely new flight. JustFly was absolutely awful to work with and showed neither remorse nor compassion.

It was a smooth flight and the crew were quite attentive.

I didn't like the confusion of boarding. We stood in a long line for quite a while before boarding began. There were three other lines going to other destinations, which made it confusing and packed with people. Check in was a little stressful as well. Due to a belt malfunction, we had to wait in line for a long time without any information. Once we were able to check our bags, my husband's bag was declined. We had to wait in another line before finally getting the go ahead to go to customs. For the amount of money I paid, I thought a snack would have been provided.

Second time I have flown to Brussels with Iceland Air. I love their customer service and especially the flight route. My flight going over was cancelled due to weather. I called their reservation office , had to wait on hold for 1 hour and 15 minutes , but it was worth it. The reservation agent found me a new flight on LH, she explained I would get a conformation about 3 hours after our conversation with the flight information and new txt information. I was able to check in with LH on line that evening. Iceland Air had every pre assigned seats for me.

The boarding process in Kevlavik is pretty awful. No seating around gate areas. You have to stand in line for about 30 minutes to then have to get on shuttle to be driven to plane where you have to walk on stairs to get to plane, or in some cases you actually get to board from the terminal, which happened yesterday. I have MS,and sometimes standing for long periods of time and then having to climb up stairs is difficult for me. I also see a lot of elderly people and parents with babies having difficulty with this boarding process. Their airport really needs major expansion for the amount of people that travel thru their. Seating araes around their gates should be a priority.

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

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 prices, so it’s not possible for us to guarantee what other companies are selling.

We aggregate tons 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 don'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.

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.
