Flew with Air Koryo from Beijing to Pyongyang on 29/12/16. The flight left late and arrived late but as we were the only flight for the day it didn't matter much. The burger was quite tasty & the drink was ok. Service was good & entertainment was watchable, the seat was also comfortable. All in all for a 2hr flight it was perfectly acceptable and I would happily fly with them again, although the check in & Chinese immigration process is quite lengthy so allow plenty of time before the flight.
