The memorandum of understanding was signed at the Farnborough International Airshow in Hampshire, U.K. Walter Cho, chairman of Hanjin Group, and Stephanie Pope, president of Boeing Commercial Airplanes, attended the ceremony.
These long-haul, wide-body aircraft are expected to play a crucial role in Korean Air's fleet following its planned integration with Asiana Airlines.
The 777-9, featuring a wingspan of up to 71.8 meters, offers over 10 percent improved fuel efficiency compared to its predecessors. It can fly non-stop from Incheon to any U.S. destination with a range exceeding 13,000 km and typically accommodates 400-420 passengers.
The 787-10, Boeing's largest 787 variant, can transport 15 percent more passengers and cargo than the current 787-9 model. It boasts 25 percent better fuel efficiency than the 777-200 and is considered Boeing's most eco-friendly aircraft.
Chairman Cho said that this acquisition would be a significant milestone in Korean Air's fleet expansion and upgrade strategy, enhancing passenger comfort, operational efficiency and supporting long-term sustainability efforts by reducing carbon emissions.
Korean Air plans to introduce a total of 203 new aircraft by 2034, including 33 Airbus A350s and 50 A321neos, as part of its fleet modernization initiative.
