My seat was unusually narrow. My hip bones touched both armrests. I've never encountered that on any commercial flight in my life. It was a middle seat ahead of an emergency exit row, so maybe that's why? All I know is that it struck me as extremely strange and not pleasant.

My seat was unusually narrow. My hip bones touched both armrests. I've never encountered that on any commercial flight in my life. It was a middle seat ahead of an emergency exit row, so maybe that's why? All I know is that it struck me as extremely strange and not pleasant.

Checking a bag at KEF was time consuming due to long lines despite having a business class ticket

So Iceland Air is one step above Spirit Airlines. They do not feed you unless you pay for it or are in Saga Class. So, bring your food. They have a drink service, but it's in a large Dixie cup. Ask for the can, that is the only way you'll get a real drink. Also, we missed our connecting flight so they put us up in a flea-bag motel. Don't get me wrong, the staff was nice and friendly, however, there was no shower gel or shampoo in the hotel. We have to go to the corner store to pick some up. The room was not in great shape. Holes in the bathroom, a badly repaired ceiling in the room. The window was warn out. So, you get the just of how bad it was.

The plane was flaming hot! Could not breathe. Everyone coughing from heat. Awful.

Food and staff were excellent. Seats on Saga (business class) are comparable to domestic first class of US Airlines, regarding space and recline. Entertainment options had little international component.

Flight delayed Delay to the gate upon arrival Baggage took more than an hour so we missed our connecting!!! Terrible experience!

There is no food without paying $. Only soft drinks are included in your fare.

Some drinks and basic snack will be good. Water should be served at least once an hour. Blankets for folks who might be cold.

Pros: "Flight was relatively empty. Professional crew, comfortable seats"
Cons: "I think they skipped me with food service. Checking up on passengers who may have been sleeping would be nice. Headphones need to be purchased. Limited entertainment options."
Cons: "Communication about international COVID requirements before the day of departure."
