The world’s 20 busiest air routes
The most crowded flight path on earth is a route that's only 813 kilometres long
What was the world’s most travelled air route in 2017? Heathrow to JFK? Mumbai to DXB? No.
The busiest international route last year was between Hong Kong and Taipei according to new data released by travel analysts OAG. A total of 29,494 trips were taken on this path in 2017. Interestingly, the journey is only 813 kilometres long.
The five top routes were all in East or Southeast Asia, but two Middle East flights do feature in the top 20. The route between Dubai and Kuwait sits at 15 on the list with 13,297 trips a year (with airlines including Emirates, Flydubai and Kuwait Airways), and the path between Cairo and Jeddah is at number 19 with 12,896 trips.
The list is based on the largest global routes by total number of flights (both arriving and departing), counting jet operations only.
THE DOMESTIC FLIGHTS
The top three domestic flights in the world are between Jeju and Seoul Gimpo in South Korea (64,691), Melbourne and Sydney in Australia (54,519) and Mumbai and Delhi in India (47,462).
The fact there are 64,691 annual flights between Seoul and Jeju means there are on average 177 flights on that route a day. Why is the path between South Korea’s capital and the island of Jeju so popular?
Well, its temperate climate, mountains, waterfalls and beaches mean Jeju island is a popular tourist destination for South Korea’s 51.4 million people. In fact, it’s so beautiful that it was dubbed one of the New 7 Wonders of Nature (a 2011 campaign that involved hundreds of millions of votes).
An interesting side note: Jeju province has a visa policy that is independent of the Republic of Korea’s mainland – this means that there are only 11 nations that require a visa to fly into Jeju (those that aren’t granted visa-free entry are Afghanistan, Cuba, Ghana, Iraq, Kosovo, Libya, Macedonia, Nigeria, Palestine, Sudan and Syria).
