With diplomatic relations are warming in the Korean peninsula, Air China recently resumed its regular service between Beijing and Pyongyang.
Air China resumed the flights on short-notice in early June, making it once again the only foreign airline to operate flights to North Korea. The service includes flights between the two cities three times weekly using Boeing 737 aircraft.
In November, the Chinese flag carrier suspended flights between the two cities citing poor demand. China is North Korea's biggest allies and trading partner.
North Korea has limited international air services, which for the most part is served by state-run airline Air Koryo. Air Koryo operates some flights to Beijing, and Vladivostok, Russia as well as seasonal services to cities in China. Its own service to Beijing was also reinstated after a brief suspension months last year.
The resumptions of flights and warming relations between North Korea and China, the US, and South Korea has been followed with talks to open up potential new air routes to the country from China and South Korea.
