If there was a disclaimer regarding food service or lack thereof, l missed it. If l had known l would have prepared better. Same with transferring at Reykjavik. No information about disembarking via stairs into rain, slush and puddles deep enough to swallow a foot. After being treated to haute cuisine restaurants and warm inviting environment during the flight, the airport is, let’s be kind, disappointing. Plane was comfortable, Airbus, staff were welcoming enough. I would likely try the route again. Maybe have a night and day in Iceland. Maybe not.

They had a 4 hour delay and left my luggage in Iceland and it didn’t arrive in Portland until 11/1

It was too cold in the plane my feet froze

Service was excellent. Food and drinks were very good except for a greasy lump of a donut at the end of the flight that left us both feeling internally disgusted.

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.

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!

It was good. The air plane is clean and staff were friendly.

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.

Had a few open seats and could use it for a great rest ful journey

Airline food is airline food, but the plane was wonderful and the seating comfort outstanding. One of my best flights in quite a while.

Smooth flight with enough time for connection. Ran out of meal options. In-flight and gate staff were friendly and helpful. Good service overall.

Boarding procedure should have the crew and personnel who are more trained, in a sense of precisely knowing what can be done and what cannot. They do not have the exact information on what you should do in the first place, also the boarding itself was slightly delayed due to the aircraft "not being ready".

The seat space seemed small especially when the person ahead reclined but other than that, very good.

The service and flight was great. Luggage came out very quickly!

..it was short.. I didn't like that my red bag went out completely stained with black stains..That's probably some airport staff bad handling but still

Everything went well. I will fly with Lufthansa again. And use Kayak whenever I book flights

Bought a seat in a flight that got changed out so ended up paying for a seat I would have had if I hadn't paid.

Food was poor quality and the screens for entertainment didn’t work properly
