Blackpink's global "Born Pink" tour took the South Korean quartet across the continents of Asia, Europe, Australia, and the U.S. onboard a premium private jet, the expense of which reportedly ran into hundreds of thousands of dollars.

Recently, Korean Air shared snapshots on Instagram of the luxurious jet allegedly used by the band members - Lisa, Jennie, Jisoo, and Rosé - throughout their worldwide journey. The airline also publicized the availability of the private jet as part of its elite services.

The girls' record label and management firm, YG Entertainment, allegedly splurged a sizable fortune to charter the private jet from Korean Air. This airline runs a membership model that amounts to roughly KRW 700 million ($538,422) per annum, as reported by South Korean press.

Upon subscription, members gain 30 flight hours. The hourly rate for international flights with a membership is around KRW 4.8 million ($3,693), while domestic flights cost approximately KRW 2.9 million ($2,231).

As per South Korean media, the price for chartering a private jet for international journeys could surge to KRW 844 million ($649,463) for a span of 30 hours, or KRW 28.13 million ($21,650) for each hour. Once the 30-hour allocation has been exhausted, customers need to renew their membership to continue the service.

These details could not be independently verified by the International Business Times.

Korean Air, reportedly the sole national airline providing a premium private jet service, is a favorite choice among high-profile companies and individuals. YG Entertainment counts among the airline's top clientele, alongside tech giant Samsung.

Korean Air boasts a range of private jets on offer, namely the Gulfstream G650ER, the Boeing Business Jet, and the Global Express XRS. Renting these jets entails a host of benefits such as gourmet in-flight meals, top-notch security, quick check-in and boarding, as well as lounge privileges, according to the airline's official site.

The exact model of jet used by Blackpink remains unknown. However, YG Entertainment and Korean Air inked a memorandum of understanding (MOU) this March aiming to "spread the Korean Wave culture and enhance their global status," as reported by Newsen, a South Korean news outlet.

The MOU entails in-flight entertainment features such as welcome videos starring all four Blackpink members and airing their music onboard. Korean Air has also committed to sponsoring Blackpink's ongoing "Born Pink" world tour, slated to wrap up on August 26 at Dodger Stadium, Los Angeles, California, although further dates might be announced soon.

In a recent move, Korean Air unveiled a dedicated aircraft to promote the Busan World Expo 2030, featuring the faces of Lisa, Jisoo, Jennie, and Rosé emblazoned across the plane's exterior.
