This was my return flight and it was 100% different than my out bound. Better seats and great food for sure. As i was disappointed last time but this time they made up for it

Flight was good but the passport control in airport for outbound passengers was a mess, fortunately they pulled passengers making connections to this flight for expedited processing so we made the connection.

Bid process for upgrade is very frustrating. I was notified that I had won the bidding, then was told there was no seat available.

You cancelled my flight and didn't arrange another. Sent no info except YOUR FLIGHT HAS BEEN CANCELLED. HERES WHAT TO DO NEXT. and the rest of the email was blank???

Yes avoid JFK airport at all costs. A horror to navigate.

Really like this airline. Best food for airlines and comfortable seats and attentive staff. Delay was due to air traffic.

great crew, professional, funny, and great service. good condition plane too! great experience

Very difficult to clearly hear the dialogue on videos due to airplane engine sound. Flying to Copenhagen audio was very clear. Food was excellent. Returning flight--Lunch and breakfast food was the worst I've experienced. Audio was terrible. Why the difference?

Travelling coach, comfort is all in one's perspective. Movie choices were great. Food was OK. Flight crew were pleasant. Tip: If they come through asking if you want tea or coffee, do not ask for water. They get miffed. So use the call button after they pass through.

Food was underwhelming. One free coke, charged $$ for one wine. Last year one wine was included. And prices were much lower.

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.

Terrible way of boarding in Reykjavik. Seats comfortable. Meal was good.

Unlike my prior three connections on this latest journey, this flight was fairly good. Only issue was boarding as it was once again one of those Icelandic issues of bunch up, walk in the rain to a bus that then has you run up three flights of stairs to board the plain. I was in Saga class but the bus scramble eliminates any chance you get on first and have to then find a place to squeeze your carry on into an overhead that the people in economy populate so they can grab it on their way out up front. But unlike other Icelandic flights this journey I did find more the of the business class like accommodations then the other air segments. This one found a pillow and blanket waiting for me and I actually received a small cup of sparkling wine and had a bottle of water in place. Service was attentive and the flight departed and arrived on time. Received a menu and had choices of a hot or cold meal. I choose the hot which was cod and it was good. Decent size portion, salad and a choice of dinner rolls. Beverage menu was a selection of wines, beer and soft drinks. Desert was a small Tiramisu. Overall the six hour flight was a good experience for the price point.

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!
