Flight was ok but the food was poor, and the business chairs were not comfortable.

Seat did not recline. Only water, tea, and coffee were complimentary

Great experience in Saga Premium. Food was tasty and felt fresh. Seat was comfortable (enough) - would have wanted a layflat seat.

The flight itself was excellent, but getting to the plane was literally an exercise in pain. My wife needs a wheelchair and can only stand/walk for short periods before having extreme pain. We had to take a bus to a loading platform and use a terrible elevator to get up to the plane. Meanwhile the rest of the bus were using the stairs. This meant the people who needed to sit down were stuck standing at the end of the line while everyone else boarded. My wife was in agony.

It was amazing. I sat in First Class as a Saga Premium member, and my service was top notch. It was wonderful. I only recently joined Saga Club since I do travel to Scandinavia often and enjoy flying through Reykjavik on Iceland Air versus other ways of travelling to Europe. This was my first trip sitting in first class, which I honestly wasn’t expecting!

There were no places to sit at the gate. Most people had to sit on the floor or stand waiting for the gate to open and board. We were told we needed passport and the person hardly looked at them. Maybe for 2 seconds. No announcement made asking to board by row or group. On a 5.5 hour flight the crew only came through the cabin 2 times offering water and buy everything else. For the price of the ticket at least offer free soda! The airliner was very comfortable

Kayak moved my flight up 9 hours although I had another flight with Kayak from Iceland, which meant I could not catch the changed flight. This resulted in having to get a hotel overnight. I had to arrange the changes through the airline directly because the Kayak site was not user friendly.

Excellent. We flew Saga class and loved the delicious meals and the comfy seats. The lounge at KEF was wonderful as well.

Crew was wonderful. I knew going in that the seats were not lie-flat in business class, but they reclined less than I expected. To save on waste, you have to ask for which pieces of the amenity kit you are interested in, which they will gladly give to you. Flight was fairly short, so no issues. I did have one piece of luggage not show up at terminal on landing. They were great about looking for it. Found it...it actually did make the flight and was listed as "not picked up" (?????--we stayed over an hour looking for it, including in the odd-sized baggage claim.) Since "not picked up" they will not ship to my house and I have to go back to airport, which is in another town. I probably could have pressed this issue, but headed back to airport for another flight anyway, so will pick up then.

Screen didn't work, and neither did the button to tilt the seat even though the seat was comfortable
