- Korean Air will use a 1 percent SAF blend on flights to Kobe and Osaka (Sept 2025–Dec 2026) after a successful trial on the Incheon-Haneda route.
- The SAF, made from used cooking oil by local suppliers and ICAO-certified, cuts emissions by up to 80 percent and supports aviation decarbonisation.
Korean Air has expanded its use of domestically produced sustainable aviation fuel (SAF), introducing a SAF blend on flights to Kobe and Osaka.
The airline first trialed locally produced SAF on its Incheon-Haneda route from August 2024 to August 2025, successfully verifying the fuel’s safety and performance. SAF, which can reduce life-cycle carbon emissions by up to 80 percent compared to conventional jet fuel, is considered a key component of the aviation industry’s decarbonisation strategy.
Korean Air will use a 1 percent SAF blend on flights from Incheon to Kobe (KE731) and Gimpo to Osaka (KE2117) from September 19, 2025 through December 31, 2026. The programme will cover approximately 90 flights on the Kobe route and 26 flights on the Osaka route.
The airline’s SAF is sourced from domestic suppliers HD Hyundai Oilbank and GS Caltex. Produced from used cooking oil (UCO), the fuel is certified under the International Civil Aviation Organization’s (ICAO) Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA).
This initiative reflects Korean Air’s commitment to driving sustainable aviation in Korea and supporting global efforts to achieve carbon neutrality.
