Air Koryo. DPRK National Airline.
An expatriate friend of mine who lives in Beijing and is CEO of a company doing business in North Korea informs me that he has flown in excess of one thousand ( 1000 ) flights with Air Koryo the national airline of North Korea. The first was in 1993 and he is still doing it. The majority of these flights were Beijing - Pyongyang - Beijing on the IL62 when until recently it was taken off passenger routes and replaced by the TU-204. He describes Air Koryo as his favourite airline for reasons of punctuality, inflight service and the big smiles he gets from the girls. Having flown with Air Koryo I can't do other than endorse his sentiments.
