Behind the scenes, the airline industry is aggressively pushing for homegrown alternatives to petroleum-based jet fuel. Though supplies will not be ready for several years, a coalition that includes the Federal Aviation Administration, airline, manufacturing and airport associations wants standards for a 50 percent synthetic jet fuel approved by the end of the year.
