Was hard to sleep, but other then that everything was good.

We got to the runway and had to go back to terminal to have plane worked on, which is fine, but the 40 minute connecting flight was already gone because of this delay and had to wait 5 hours to get on a different flight and only got a meal voucher which I didn’t see the email until after I had already ordered and paid for food. I feel I should be compensated.

You should offer more than 1 cup of water on a 2.5 hour flight.

Staff is all professional and courteous. Boarding was unnecessarily chaotic and painfully slow; planes are basic - no food (not even peanuts), no regular usb chargers (only new usb-c), movie choice is tiny with nonstop adverts… but clean plane and very nice staff.

Hard to figure out how to put back the seat, how to get the entertainment, how to upload passport docs. Also, a warning in the airport that food was all for purchase would have been helpful.

The flight itself was fine—typical tight legroom and no complimentary food. The real issue was that it wasn’t my original flight. Icelandair cancelled my initial booking, forced a rebooking through a different airport, and then cancelled the new connection as well. Not exactly a dependable experience.

Horrible. My dad was recently hospitalized and diagnosed with lymphoma and Icelandair refused to refund flight even though I had a letter from his physician.

Best smelling onboard bathrooms ever. Even after use the whole flight. Biggest overhead bins. Most legroom in economy class. Great Icelandiic music. Really nice staff. Icelandair is awesome! (Don’t fly Air Canada! During the strike they lied about no flights available (I booked this flight myself) and hid the process to get money back on their website by obscuring menu titles, then made it difficult and time consuming to fill out. I’m Canadian. Don’t trust Air Canada!

Boarded with no problems. Sat on the tarmac for an hour before taking off. We were the last ones on our connecting flight. Didn't think we were going to make it. Our flight to Iceland was similarly delayed. When we've flown other airlines, pilots have tried to make up time while in the air. This doesn't seem to be something that Icelandair does. We made all of our flights, but it was stressful and we didn't think it was going to happen based on the time we arrived.

Did not like last minute change to our itinerary that made us spend the night in the airport
