The world's busiest international passenger route averages 80 flights a day, or one flight every 18 minutes. 

In July alone, a total of 451,801 passengers travelled the 802km route. 

The route in question which claims the title as the busiest air corridor on -- or above -- earth? Hong Kong to Taipei, Taiwan. 

That's according to a World Routes 2017 ranking which was revealed at the 23rd edition of the World Route Development Forum in Barcelona over the weekend, a global conference attended by 275 airlines. 

The busiest international routes were calculated using statistics from air travel intelligence company OAG. 

A scan of the top 10 list shows that the busiest air routes are all located within Asia. 

The carrier that offers the most capacity on the Hong Kong - Taipei route is Cathay Pacific Airways with 309,439 seats, followed by China Airlines, EVA Airways, Hong Kong Airlines and Cathay Dragon. 

Meanwhile, the most expensive route in the top 20 list is Hong Kong to Beijing, averaging $333.08 on carriers like Cathay Dragon, Air China, Cathay Pacific, China Southern Airlines and Hong Kong Airlines. 

At the other end of the spectrum, the Palma de Mallorca to Dusseldorf itinerary emerged the cheapest.
