United Airlines has expanded its partnership with sustainable aviation fuel provider Neste to provide SAF to three more U.S. airports, the fuel producer announced Tuesday.
Neste began SAF deliveries to Houston's George Bush Intercontinental Airport in July, and those will continue until the end of October 2025, according to the company. SAF deliveries to Newark Liberty International Airport and Dulles International Airport began in September 2025 and are to continue through the end of the year.
The fuel is delivered to each airport via existing pipeline infrastructure from Neste's SAF terminal facilities in Houston, according to the company.
United also uses SAF from Neste at Chicago O'Hare International Airport and at San Francisco International Airport, according to Neste.
