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.

Literally nothing

The seat was uncomfortable, the service was slow, both my flights (Newark to Reykjavik and Reykjavik to Heathrow) were delayed and the flight staff was incredibly poor about providing us updates not to mention any accuracy with the timing. Overall, my experience with Icelandic Air was so bad I will never fly with them again.

Baggage delayed at Newark so that I only got my bag an hour after landing. Also half hour wait to get to the gate. This meant that I missed my train connection nd had to pay an additional $75. I simply won’t take this airline again and flying out of Newark as a Philadelphia resident is not that convenient either.

That food and drinks, including wine, were served for free. That the on board entertainment had lots of options that were well rated, recent, and were all free. The touchscreen was the best I've seen so far on airlines

The flight map was not working and the attendant didn't know what we were flying over (probably Greenland).

Very helpful and courteous staff.

I don't like that the armrests between seats don't go up all the way. That makes it impossible to stretch out if there's an empty seat next to you. Also, there's too big of a space between the window seat and the window, so you can't lean your head against the side of the plane to take a nap.

in flight experience is above average

The computer system really needs a lot of improvement. We were checking in with our infant daughter and it took 50 minutes to check in with a senior person helping the check in person and phone calls to their technical assistance. We were told an infant is difficult in their system, and our dual national daughter was another layer of complication.

Good 6.6

The flight crew from the mel to lax route were excellent. One was especially attentive to my 2 toddlers and gave me a bit of a break, something that has NEVER happened in over 40 flights traveling with children.

I think something was broken in our section (mel to lax) as it was uncomfortably hot and the flight crew tried to get it cooler but could not. I’ve never experienced a flight that was too hot, usually the opposite. It was stifling.

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.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days.
