Jeju Air also uses 'Korean language' for in-flight broadcasts..."A seat belt instead of a belt".

Jeju Air announced that it will broadcast pure Korean on all flights to celebrate Hangeul Day.

The seat belt is a seat belt, and the overhead shelf on the plane is changed to Sirung, and all foreign words and Chinese characters used on the plane are changed to Korean.

In addition, Jeju Air will hold a quiz where passengers will match the meaning of pure Korean words during the flight and distribute the exclusive font "Flight Sans" free of charge on its official website.
