Airline reviews

Crew was wonderful. I knew going in that the seats were not lie-flat in business class, but they reclined less than I expected. To save on waste, you have to ask for which pieces of the amenity kit you are interested in, which they will gladly give to you. Flight was fairly short, so no issues. I did have one piece of luggage not show up at terminal on landing. They were great about looking for it. Found it...it actually did make the flight and was listed as "not picked up" (?????--we stayed over an hour looking for it, including in the odd-sized baggage claim.) Since "not picked up" they will not ship to my house and I have to go back to airport, which is in another town. I probably could have pressed this issue, but headed back to airport for another flight anyway, so will pick up then.

It didn't happen. Icelandair cancelled the flight from Nuuk, Greenland to Reykjavik, Iceland so I couldn't fly to Portland. Additionally Icelandair rebooked me on a flight that got cancelled too.

The ticket was reserved in my name but not paid for by underpricer. Alaska airlines was unable to issue my ticket (could not connect the ticket with the PNR) due to an error with underpricer and I spent the better part of 2 hours at the ticket counter trying to rectify.

The Icelandair crew was so kind!!! Thank you for making my first trip to Paris a great one!

I am not going to fillo this out for each leg of my trip. My first review holds for the experience

They wouldn’t check in my luggage even though I had one checked bag prepaid. So I took my bag to the gate and tried to check it in there and two employees scolded me for bringing a large bag to the gate. I told them I was trying to check it in and that it was prepaid, and they said they couldn’t guarantee that it would arrive at my destination but they finally let me drop it off when boarding the plane and pick it up right after exiting the plane. There was no food, and there was no entertainment.

The boarding process seem to take longer than necessary, resulting in a 20+ minute delay

One of the worst airlines I ever flew. Boarding is a disaster, they are always late, the planes are overly crowded. Everyone on my flight lost their connection because they were 2h late. Reykjavik is also not the best airport out there.

Flight was delayed. They did a terrible job rebooking me. Agent on the ground was useless. The partner airline who ran the plane was able to help me but Iceland air was useless

Flight delayed Delay to the gate upon arrival Baggage took more than an hour so we missed our connecting!!! Terrible experience!
