Busan was one of 4 cities competing to host the 2030 World Expo. Korean Air was a partner of the bid; in the meantime the airline also acted as a sponsor of the 2023 World tour of K-pop girl band Blackpink and it was decided to affix both decals on the same plane. Riyadh was chosen to host the Expo in late 2023 and the stickers were quickly removed thereafter.
