Handling our luggage was the biggest issue - they lost it and we got it almost 3 days later. Really threw off the beginning of our trip and we really had to change our itinerary accordingly.

Handling our luggage was the biggest issue - they lost it and we got it almost 3 days later. Really threw off the beginning of our trip and we really had to change our itinerary accordingly.

Seat was hard and uncomfortable and the temperature too warm and uncomfortable.

No meals included on this long international flight. Most airlines will offer you a meal when flying internationally. Not Icelandair. Your included choices are water and coffee. Poor customer service. The airport was also very confusing.

I flew Icelandair with my partner from Prague to the US. Overall flight time was around 12 hours, with a connecting flight in Iceland. I have flown internationally for years and with multiple airlines. Every airline serves you a meal when traveling internationally. Icelandair not only did not offer an inclusive meal, but they did not even offer a snack. The only things they served over our long flight was water and coffee. Ridiculous! Never again will I fly with Icelandair.

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!

Worst airline I’ve ever flown. Delayed 5.5 hrs, missed connecting flight, and missed an entire day of vacation. Zero customer service

Everything sucked. No food, one small glass of water, a tiny coffee, 5.5 hour delay with no customer service. Would never recommend flying them.

The crew was wonderful at check in, the gate and on board. Felt the luggage had more room than the passengers. The seats were smaller than most domestic U.S. airlines. I'm only 5'2" and I had little legroom. There were only 2 bathrooms in coach. Needed more. The flight was very smooth but not the most comfortable.

There was no lounge at Boston for us to use. Typically flying first class overseas comes with lounge privileges. The seats did not recline even a little. My headset only worked on one side. I felt like I was flying on Ryan Air, not Icelandic Air.

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.
