As U.S. Airlines Carry More Passengers, Jet Fuel Use Remains Well Below Its Previous Peak

The amount of jet fuel consumed by U.S. airlines increased in both 2015 and 2016, although jet fuel use in 2016 remained 11% lower than its level a decade ago.  Jet fuel use was lower despite the fact that the number of passengers traveling on U.S. carriers in 2016 was 7% higher than in 2007.

Jet fuel consumption has not increased as much as air travel because airline fuel economy has continued to improve.  Air travel fuel economy generally increases as carriers review their commercial fleets to modernize them through purchases or leases of new, more fuel-efficient planes.

Since 2007, the average fuel economy of U.S. carriers—in terms of available seat-miles per gallon—has increased from 52 available seat-miles per gallon to 63 available seat-miles per gallon in 2016, up 22%.  Similarly, the average fuel economy of U.S. carriers—in terms of revenue seat-miles per gallon—has increased from 41 revenue seat-miles per gallon in 2007 to 53 revenue seat-miles per gallon in 2016, up 27%.  The larger gain in fuel economy measured using the revenue seat-miles per gallon metric reflects the effect of increased load factors in reducing the amount of fuel needed to move paying passengers to their destinations.

Many aircraft manufacturers have plans to design, re-engineer, and deliver more energy-efficient aircraft and engines into service using advanced manufacturing and engineering.  New aircraft, whether acquired to expand capacity or replace existing capacity, are more energy efficient than the average aircraft in the existing commercial fleet.
