Pros: My flight going to London was a train wreck...missed connecting flight, awful service and charged extra for a backpack that was called ”oddly shaped.” However, the return flight was the exact opposite, amazing service, free check-in because of my experience earlier and upgraded seating. I appreciate that they corrected what had gone wrong. Nicely done!

Pros: Loved Finnair. Hated Justfly.com. If you own this company, you need to end up like Blockbuster or Circuit City.

Cons: If I would have purchased my tickets from Finnair.com, I would have had a much better experience. Kayak found me a good price but purchasing the tickets through Justfly.com was the biggest mistake of my life. The trip ended up costing me $285 more than what I budgeted and there was zero customer ser

Pros: It was all a smooth operation. In particular I appreciated that since my flight from Chicago was delayed and I missed the original connection, as soon as I disembarked in Reykiavick I found an SMS saying that I had been moved to the next available flight, and they even gave me a food voucher.

Cons: They don't give you food on the flight unless you pay which in principle is not a bad thing, and makes for a quieter flight, because it's not the case that everybody is eating, and eating at same time. On the other hand on a long transatlantic flight even a small snack would be appreciated.

Cons: We paid extra for an exit row with more leg room and were moved to a standard seat. We were also separated from the rest of our party. We spoke to the help desk to try and resolve the issue they told us the seats we were moved to also had extra room but when we boarded the plane this was not true.

Mediocre 2.0

Cons: After paying for 2 seats next to each other, Iceland Air decided to change the aircraft and reboked us on regular seats. I am 6ft6 with bad back therefore booked the extra legroom seats and want to have my wife next to me to assist me with putting the carry-on lugage up in the spaces above. We ended up sitting 3 seats apart, I was in the extra legroom seat but in a middle seat,so I could not put my feet in the isle to prevent leg cramps. When we boarded the flight from Reykjavik to Boston I notified the stewardess and she assured she would help, but I never saw her again and no one came to our help. Also when we entered the REK airport after flying from Amsterdam we were not notified to keep our passport on us, as we needed to go tru another checkpoint. My wife had our pasports and went to check some shops, while I was reading a newspaper. After noticing that I could not go to the boarding area for our next flight, I was able to locate my wife and we barely made it to the gate in time.

Pros: The crew tried to be helpful and the flight was on time and uneventful.

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.
