In the Summer of 2025, United Airlines (UA) and Neste brought sustainable aviation fuel (SAF) to these three airports for the first time: Houston George Bush Intercontinental Airport (IAH) in Houston, Newark Liberty International Airport (EWR) in New Jersey, and Washington Dulles International Airport (IAD) in Washington, DC. The partnership represents the first time that any airline has operated to the three hubs, flying on SAF.

The new locations build on the successful SAF operations at Chicago O’Hare International Airport (ORD) and San Francisco International Airport (SFO) where Neste have been supplying UA since last year. The term of the SAF contract at IAH is until the end of this month, while EWR and IAD are scheduled for SAF flights until next year.
