Hawaiian Airlines Uses SAF on Osaka-Honolulu Route

Hawaiian Airlines has begun using sustainable aviation fuel (SAF) on its flights between Osaka and Honolulu, marking a key step in the carrier’s decarbonization efforts. The initiative is part of a partnership with Cosmo Oil Marketing and Hawaiian’s parent company, Alaska Air Group.

The SAF is produced from used cooking oil and represents the first time mass production of this fuel has been carried out in Japan. By blending it with conventional jet fuel, Hawaiian aims to reduce lifecycle carbon emissions significantly on its long-haul services. The airline said the agreement highlights its commitment to advancing cleaner aviation and supporting international collaboration to scale up SAF supply.

The move also aligns with Japan’s broader sustainability goals, as the government and industry stakeholders push to expand the use of SAF to meet emissions reduction targets. For Hawaiian Airlines, it provides both an environmental benefit and a demonstration of how regional cooperation can accelerate adoption of greener fuel solutions.

Hawaiian operates regular services between Japan and Hawaii, a key market for tourism and business travel. By integrating SAF into its Osaka–Honolulu flights, the airline is not only cutting emissions but also setting a precedent for future expansion of sustainable fuel use across its network.

The carrier emphasized that broader availability and affordability of SAF remain challenges but said initiatives like this partnership are essential to achieving long-term sustainability in aviation.
