SEATTLE, Wash. — The first commercial airline flights in the U.S. to use biofuel produced by Dynamic Fuels LLC, a joint venture of Tyson Foods and Syntroleum Corp., began this week in Seattle.
Alaska Airlines initiated two flights on Nov. 9 using a 20 percent blend of renewable jet fuel from Dynamic Fuels’ Geismar, La., plant.
One flight involved a Boeing 737 Alaska Airlines flight to Washington, D.C., while the other was a Bombardier Q400 trip to Portland operated by sister carrier Horizon Air. The flights were been selected to demonstrate the use of biofuel on a transcontinental route. . .
