The flight from Seoul to Jeju Island is recognized as the most popular air route in the world. In 2017, 11 million people made this journey, according to The Independent.
London-Paris and Beijing-Shanghai routes are no longer the most popular and therefore the busiest in the world. South Korea takes the crown. In 2017, more than 11 million people traveled from Seoul to Jeju Island. Flights are so popular that departures occur every 15 minutes. The flight takes just under an hour. A one-way ticket costs approximately 9,000 rubles in Russian currency.
The busy route is due to Jeju's popularity among Chinese tourists. They are attracted by its visa-free travel and the large number of casinos, which are prohibited in China itself. Jeju is also popular among South Koreans, being marketed as a local Hawaii. The province is also South Korea's only special autonomous region, allowing citizens of most countries to visit visa-free.
In 2011, Jeju City was named one of the New 7 Wonders of Nature. Its main attraction is the 950-meter-high Hallasan Volcano, the highest peak in the country. A lake sits at the summit. Tourists also visit caves and the "Land of Love" theme park, which features 140 sculptures depicting people in various sexual positions.
The second most popular flight is between Tokyo and Sapporo, with 8 million passengers flying this route in 2017.
