I’m considering never flying with Iceland Air again. The seats in economy are torture. Now you only get water, coffee and tea for free- really? No food, not a single peanut. The passport line was insane, everyone was worried about catching their connecting flight. This was the third time I’ve barely made my connection, had to run. It can’t be that my choice is to use the bathroom (during the 50 minutes between flights) or make my flight. SO stressful! Ugh.

The most uncomfortable seat i’ve ever had on a flight

Waiting area on top of stairs before Boarding the bus wasn’t great. Took a long time to load the bus to gate.

The real reason why the flying experience with Icelandair ---was mediocre was because of not being able to enter DC airspace yesterday evening. This obviously was out of your control and do realize this is a safety issue. I did notice---that everything was being done to get us to Washington Dulles and we did arrive at Dulles SAFELY with just a 4 hour delay. Thank you!

Iceland Air severely damaged a checked bag. Additionally, the gate agent caused issues for many passengers who had standard-sized onboard bags that would have passed inspection by any other airline.

Nice, quick flight. There were lots of empty seats so they told me I could sit next to the emergency exit where I would have more legroom.

The staff was kind and helpful. There was no food, and you needed to bring your own earphones to use the entertainment, which I didn’t know.

Overall satisfied and would fly with them again. They could improve the check-in efficiency at BOS, we got backed up because it seemed there were passengers requiring much more time for check in.

The customer service was unbeatable from the wheelchair assist team to the flight attendants. The pilot also did an excellent job managing the turbulence.

Delays at check-in, seemed like they were short ground staff at the time and some passengers needed extra processing.
