Icelandair flight was excellent. The checkin and security arrangements for Saga Premium passengers at Newark was very poor - our checkin opened much later than the normal and our security queue simply led us to the back of the normal queue. Someone was having a laugh surely!

Icelandair flight was excellent. The checkin and security arrangements for Saga Premium passengers at Newark was very poor - our checkin opened much later than the normal and our security queue simply led us to the back of the normal queue. Someone was having a laugh surely!

Never took flight. See previous comment on trip from Boston to Reykjavik. Used a different airline that i had to find and book.

The flight was on time and the crew was nice. I did not like the fact that my husband and I were seated in different rows. I feel pressured by airlines to pay more to choose our seats. We will sit anywhere, but we shouldn't have to pay to sit together. I also think they should serve at least a snack that's free.

My only area of issue was the flight was rather warm and the knobs for cool air didn't allow much cool air to come through. Everything else was great.

Everything was great! My only critique is 25 euro for wifi is wild, but I get it

Good, but I feel there should be a separate boarding line for seniors

Easy check in and boarding. Staff pleasant and helpful. Will continue to fly with Iceland air. Aircraft clean

Plane left an hour late and missed our connecting flight. Your service center was closed ao Alaska Airlines could not change the ticket. Thus we missed the chance to get out that night to San Jose. This is a major operational blunder.

Well! They got me as far as Iceland, let me wait around at the airport since my next flight had either left or canceled, finally gave me my luggage, and sent me to wait quite some time with seven other people for a ride to a hotel. At the hotel we got a chef's salad, a nice room for the night which unfortunately had feather pillows and duvet (allergies), a really great and spectacular buffet for breakfast (small but stunning), taxis back to the airport for the 9:30 Delta flight back to Minneapolis. The Delta flight has free food and liquor included which Icelandair does not. All in all, it falls far short of my worst ever United flight to SGN. Icelandair did change my reservation after my roommate tested positive for COVID and we canceled our plans to travel around Iceland, but the charges were fairly hefty. I had trouble contact Kayak's agents to discuss changing my reservations and finally contacted Icelandair who changed them. (I used their contact form and put in several requests for call backs.) Of course, they called just after I made the change with Icelandair.

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
