(CNN) - The U.S. may have the world's largest aviation market, but it's Asia that rules the skies when it comes to in-demand air routes.
A new survey to identify the planet's busiest passenger flight routes reveals a list largely made up of Asian destinations, with the 450-kilometer journey from Seoul's Gimpo Airport to the island of Jeju, located off the coast of the Korean Peninsula, coming out on top.
Last year more than 13.4 million people traveled the short haul route from South Korea's capital city to the idyllic island, dubbed "the Hawaii of Korea."
The hugely popular journey has an average of 180 scheduled flights each day, or one every eight minutes.
Its nearest rival was the Melbourne Airport to Sydney Kingsford Smith Airport route which transported just over nine million passengers in 2017, according to the study by UK-based aviation network developer Routes.
In total, Asia-Pacific accounted for more than 70% of the 100 busiest routes by passenger numbers.
Unsurprisingly, Japan was declared one of the busiest destinations in the world, with three of its domestic flight routes among the most popular -- Sapporo's New Chitose Airport to Tokyo Haneda Airport (8,726,502 passengers,) Fukuoka Airport to Tokyo Haneda (7,864,000 passengers) and Tokyo Haneda to Okinawa's Naha Airport (5,269,481 passengers.)
Vietnam also featured, with the route from Hanoi's Noi Bai Airport to Ho Chi Minh City's Tan Son Nhat Airport taking seventh place, with more than five million passengers.
Meanwhile Hong Kong International Airport to Taipei Taoyuan Airport was named as the busiest international route, with 6.7 million passengers flying the 802-kilometer journey lin 2017.
In demand routes
The route from New York's John F. Kennedy Airport to London's Heathrow Airport was the ninth busiest international route, carrying just under three million passengers in 2017 while the journey from JFK to Los Angeles International Airport was the busiest within North America.
The study also looked at the fastest-growing routes, with the Thai domestic trip from Bangkok Suvarnabhumi Airport to Chiang Mai International Airport taking first place.
"This research backs up forecasts that the Asia-Pacific region will be the biggest driver of passenger demand over the next 20 years," says Steven Small, brand director of Routes.
The results were calculated by Routes using OAG Schedules Analyser to determine the top 500 routes by overall seat capacity in 2017. This data was then ranked by passenger numbers using figures provided by Sabre Market Intelligence.
