Overall, air travel in 2012 was higher in all regions of the world compared to 2011, with significant growth observed in Asia (9 percent) and Latin America (6 percent)

 It may not be the first corridor that springs to mind, but according to the number-crunching of an air travel IT specialist, the route between Seoul and the honeymoon capital of Korea, Jeju island, has emerged as the busiest in the world.

In 2012, flights between Seoul and Jeju shuttled a whopping 10,156,000 passengers between the two cities, marking a two percent growth from the previous year.

In fact, the world’s busiest air routes by passenger volume are dominated by Asian domestic travel, says the report from travel industry IT provider Amadeus, as seven of the top 10 corridors can be found in Asia, particularly within Japan.

After Korea, the next busiest routes are Sapporo to Tokyo; Rio de Janeiro to Sao Paulo; and Beijing to Shanghai.

The report also found that the Middle East is becoming an increasingly important global air travel hub, with Dubai, Doha and Abu Dhabi seeing 50 percent of its total air travel volume using the airports to connect.

Furthermore, while traffic volume between Europe and Asia is growing 7 percent year over year, the report  found that when flights between these two locations were routed through the Middle East, that figure grew to approximately 20 percent between 2011 and 2012.

About 300 ‘super routes’ also attract 20 percent of all air travel, carrying more than one million passengers a year.
