What’s the busiest air route in the world? Sydney to Melbourne? New York to Washington DC? London to Paris?
The correct answer will surprise you. The most in-demand flight on Earth is actually the 450km hop from Seoul Gimpo International (stop sniggering) to Jeju International. More than 11 million journeys were made between the two South Korean airports in 2015, the International Air Transport Association (IATA) reports, and with a one-way capacity of 6,561,314 for 2016, according to aviation number crunchers OAG, that figure could yet rise to 13m this year.
Second on IATA’s list is Sapporo-Tokyo Haneda, with 7.8m. But the Sydney-Melbourne route’s reputation as one of the world’s busiest is well deserved, coming in at fourth place. That’s a high ranking considering the comparative sizes of the Australian cities to other destinations on the list.
