Alaska’s planes on average can fly a passenger nearly 76 miles on a gallon of aviation fuel, the study shows.
The worst of the major carriers, Delta, flies a passenger just 60.4 miles on a gallon of fuel. American Airlines is barely better with a 60.5 mpg-per-seat rating.
Second to Alaska’s 75.9 miles per seat was JetBlue Airways’ 71.7 miles per seat.
The Wall Street Journal, which analyzed the DOT figures, credits Alaska’s relatively young fleet (7.5 years on average) and its advanced fuel-saving routing for cutting fuel consumption per passenger. The airline standardized its fleet on Boeing 737s two years ago .
