OAG’s rankings offer a noticeably different picture compared to the world’s busiest airports as determined by Airports Council International, which take into account total annual passenger traffic.

Atlanta’s Hartsfield-Jackson remains the busiest in the world, welcoming just under 104 million passengers in 2017, followed by Beijing Capital airport and Dubai International.

Asia-Pacific notably also accounts for eight of the 10 busiest international routes in the world, according to OAG’s Punctuality League published earlier this year. As previously reported by Business Traveller, Kuala Lumpur-Singapore took the top spot from Hong Kong-Taipei for the period of March 2017 to February 2018.
