Current sustainable aviation fuels (SAFs) are limited to a maximum 50% blend with conventional jet fuels because most of them lack a key ingredient―aromatic hydrocarbons that cause seals in engines to swell and prevent fuel leaks.

The leader of Alaska Airlines talks with ATW Editor-in-Chief Karen Walker about 2022 goals, customer service, sustainability and innovation.

Cathay Pacific is launching a corporate sustainable aviation fuel (SAF) program, allowing companies to purchase SAF for their employees’ flights and reducing Scope 3 carbon emissions from business travel or cargo transportation.

The governments of Singapore and New Zealand have signed a memorandum of arrangement (MOA) to drive the development of sustainable aviation between the two countries.
