Korean airlines provide bibimbap as airplane food.

First introduced to the Korean Air passengers in 1997, and immediately winning the Mercury Award chosen by the International Travel Catering Association, the bibimbap for flight has since enjoyed a constant popularity as one of the most favorite in-flight meals. The menu has been adopted by many airlines with inbound and outbound flights in Korea. Basically comprised of a bowl of meat and vegetable toppings, a warmed precooked rice, with gochujang and sesame oil served separately. The gochujang sauce, usually stir-fried with ground beef, is so popular that many passengers buy various brands of gochujang in tubes at duty free shops.
