Great planes. Great air crew. Great ground staff. Seats are large and comfortable. Crew does a great job of making sure you have what you need. Extremely attentive and professional. Gate agents are friendly and knowledgeable. They work hard to solve any problems you have - even if you're not and Iceland Air customer. I can't say enough good things about them. You can't go wrong flying Iceland Air.

Getting our bags through on a tight connection - great job Staff were helpful in finding a safe place for my bassoon.

inability to select seats without having to pay vast extra amounts of money is totally unacceptable. Ended up initially separated from my daughter and then on seats that did not recline. Flight left three hours late, nearly missed connection Next tine will fly Virgin. They look after their passengers!

Boarding process was very orderly. The 2-4-2 seating arrangement is quite nice for economy as it is a bit more spacious & comfortable. Sat in window seat with a huge compartment storage next to me by window - great for easy access to electronics, etc.. Great movie selection. Short and efficient flight and my fears about basic economy ticket were dissipated as I was able to check a bag and get better seat assignment at airport.

Slow service, not served dinner until almost 10pm. Lights were never turned down so difficult to sleep altho I had eye mask and noise cancelling headphones. Seats are not super comfortable but if you bring neck pillow and blanket it’s better.

The pretzels.

The customer service from Aer Lingus is the worst ever. This is our honeymoon and it got ruined. The flight was 3 hrs delayed, and they started rerouting people that had connection flights to London, we had a connection and randomly Wendy the service agent decide to not reroute us because we had plenty of time, of course we didn’t make the flight, we have been hostages of Aer Lingus for the last 21 hrs so far, but more will be added until we make it to Hamburg tomorrow at noon instead of tonight at 8.

Late flight. Both flights smelled of latrines. Charge for one checked back one way was 99.00. Flight attendant rude and said no vegetarian meals were available to purchase and I ordered within 10 mins of taking off. First she ignored me, even though she was talking to passenger next to me. I waited and she skipped right over me to next row. I had to press overhead light to get her attention. No veggie wrap available and I was told the vegetarian soup actually had chicken. No food is available otherwise on Iceland air flights. We almost missed our connection and flight crew didn’t even let us off plane before others who didn’t have tight connection. Husband was assigned a seat that didn’t exist on plane. Landing was the worst ever, came in on two wheels—all passengers were groaning. I travel a lot and will never choose Iceland air again.

This is one of the best airlines I've ever flown. Very nice comfortable planes. Excellent air crew. Everything they do is at a high standard. What really sets them apart is the really great service. I had a problem with WOW air not honoring my ticket due to snow. I had to book at the airport on Iceland air last minute. They didn't have a gate agent who could sell me a ticket - so they sent a manager out from the back office to book us so we would not be stranded due to WOW's incompetence. Booked us just minutes before take off, escorted us through security and onto the plane. Start to finish less than 30 minutes. Amazing service. Their class of service is far above that of major carriers. Iceland Air works harder and makes sure everything is right.

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

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 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.

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.
