Low-cost carrier Jeju Air started to sell soju on flights from Sunday.

"We added soju to our in-flight beverage menu because some passengers asked for it," a company spokesman said on Monday.

Jeju Air is the only airline that sells the traditional Korean liquor.

The company is offering it in a 220 ml plastic pouch for W5,000 (US$1=W1,102) on international routes and limits purchases to one pouch per adult.
