Just be careful, it is not business class, not flat seats, just as in comfort plus.

The food service is confusing. It was not immediately apparent which beverages were complimentary, if any.

The crew was attentive and personable. The plane was clean and the seats comfortable. It was an excellent trip!

My only area of issue was the flight was rather warm and the knobs for cool air didn't allow much cool air to come through. Everything else was great.

Been travelling for 2mo. And when you meet flight Attendants that love their jobs you can just tell. And makes flying with them worth another flight in the future!!

Most of your crew was very helpful just one young lady wasn’t, but all of the ones I dealt with were great. We had to buy food on a six hour flight and considering we had a three hour flight before this one I felt we would have a meal included. I ordered a sandwich and by the time I got it, it was quite soggy so couldn’t eat half of the sandwich. Other than the food, or lack of, the flights were great.

Late start due to so called cargo door, super expensive meals and baggage check( only airline where meals and baggage is charged on long international flights) slow baggage delivery at end a lot of employees at airport standing around talking to each other.

The cost for the flight was quite reasonable and transferring to a new flight in Reykjavík went smoothly. There was enough time to grab a bite to eat at the airport, and the luggage transferred to the new flight with no problem.

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

I didn't have food nor entertainment. Lots of leg room and seat was comfortable
