The order, the largest in the Korean air carrier’s history, is expected to include a mix of 787s, 777s and 737 Boeing airplanes, sources told Reuters earlier. Boeing Commercial Airplanes CEO Stephanie Pope and Korean Air CEO Cho Won-tae attended an event to unveil the deal with US commerce secretary Howard Lutnick.

Reuters first reported the deal earlier.

Korean Air also announced a separate deal Monday with GE Aerospace agreement on the purchase and maintenance of engines valued at US$13.7 billion.

Part of the order is re-equip Asiana, one of the sources said, a subsidiary of South Korea’s largest airline.

In March, South Korea’s industry ministry said Korean Air said it would soon finalise a US$32.7 billion deal for new Boeing and GE engines. Korean Air last year said it would order 20 777-9 and 20 787-10 planes from Boeing, with options for an additional 10 aircraft, and signed a memorandum of understanding in 2024.

Many countries negotiating trade deals with the Trump administration have announced or plan to announce significant Boeing airplane orders. Boeing has won a string of major orders in recent months.

Korean Air, a founding member of the SkyTeam airline alliance, was established in 1969 when state-owned Korean Air Lines was taken over by South Korean conglomerate Hanjin Kal.
