Air Koryo is still the worst airline in the world, British aviation consultancy Skytrax found. The North Korean carrier ranked worst for the fourth year in a row.
Air Koryo is the only airline to be given just one star (out of 5) by the Skytrax rating system. According to passenger reviews, it uses "outdated methods", for example luggage is weighed by hand and check-in procedures are "lenghty and inefficient".
Skytrax rated 600 carriers on various points, such as flight punctuality, check-in and cabin services, and onboard meal quality.
