More than 4 million travelers flew on about 30,530 flights between Kuala Lumpur and Singapore over the last year, making this air corridor the busiest international route in the world. 

In the latest report from air intelligence company OAG, analysts broke down the busiest highways in the skies revealing that once again, the world's heaviest air traffic is located above Asian countries: 14 of the top 20 routes connect Hong Kong, Singapore, and Osaka to other parts of Asia.

On average, the 20 busiest international routes have an average of more than 35 daily scheduled airline frequencies. 

The chart-topper, Kuala Lumpur-Singapore, boasts as many as 84 flights a day, with Air Asia serving the largest number of flights. 

The only long-haul route to crack the top 20 list is New York JFK to London Heathrow, which sees an average of 38 daily flights.
