Southwest Airlines partners with Red Rock Biofuels

September 24, 2014, Dallas, Tx. – Southwest Airlines has
signed an agreement with Red Rocks Biofuels LLC to purchase low carbon
renewable jet fuel. The airline's agreement with RRB covers the purchase of
approximately three million gallons per year. The blended product will be used
at Southwest's Bay Area operations with first delivery expected in 2016.

"Our commitment to sustainability and efficient
operations led us on a search for a viable biofuel that uses a sustainable
feedstock with a high rate of success," said Bill Tiffany, Vice President
of Supply Chain at Southwest Airlines. "Red Rock Biofuel's technology,
economics, and approved use made entering into an agreement for purchase a
win-win situation."

RRB's first plant will convert approximately 140,000 dry
tons of woody biomass feedstock into at least 12 million gallons per year of
renewable jet, diesel, and naphtha fuels.  

RRB's CEO, Terry Kulesa said "From the outset, we have
sought to build the best possible team of project partners. A conversation we
started with Southwest on the premise of providing renewable jet fuel at cost
parity with conventional jet fuel has evolved into a great partnership.  We're happy to help Southwest diversify its
fuel supply."

Southwest is a long-time member of Commercial Aviation
Alternative Fuels Initiative (CAAFI) which is a government and industry
coalition for the development and deployment of alternative jet fuel for
commercial aviation. As a member of CAAFI, the airline has followed the
progress of alternative fuel technologies. Red Rock Biofuels is the first
viable opportunity the airline has found to meet its financial and
sustainability objectives.
