Few people have flown Air Koryo. The North Korean carrier officially has 14 destinations in six countries. It reportedly has a fleet of 30 old mostly Soviet aircraft which are usually grounded due to lack of fuel and or parts. Video of the fleet can be found here.
Combined with an erratic schedule and a one star Skytrax rating, the airline has been described as “the world’s worst airline“.
Following a visit to the airline’s headquarters in July, 2012, by the country’s new leader, Kim Jong-un, the airline has reportedly attempted to modernise. The carrier has launched an on line booking service: www.airkoryo.com.kp giving customers “easier, quicker, reliable booking and ticketing services.” Interesting decision, seeing most of North Korea does not have access to the internet. In addition, only 2000 foreigners presently visit the country.
You can book to fly between Pyongyang, North Korea and Beijing and Shenyang in China, and Vladivostok in Russia, on the website. If you can find it. I keep finding page not found errors as I navigate through it. Others report multiple failures with the site.
