Korean Air continues to top the charts as the world's busiest airfreight carrier for the third year in a row.

The airline moved 8.68 billion ton-kilometres (tkm), according to figures compiled by the International Air Transport Association, ahead of Germany's Lufthansa with 8.07 billion tkm, reports Chosun Ilbo.



In third place came Singapore Airlines, followed by Hong Kong's Cathay Pacific Airways and Fedex.



The unit used for measuring cargo volume performance, tkm, is calculated by multiplying the volume of cargo transported by the flight distance.
