Hawaiian ranks No. 2 in study of most fuel-efficient domestic airlines

|

Hawaiian Airlines finished tied for second with low-cost carrier Spirit Airlines in a recent study of the most fuel-efficient U.S. airlines.



Alaska Airlines earned the top spot in the first-ever fuel efficiency report released earlier this month by the International Council on Clean Transportation, which made use of fuel consumption data reported by airlines to the Bureau of Transportation Statistics for 2010.

According to the study, Alaska’s in-service operations were 26% more fuel-efficient than last-place finisher Allegiant Air.

In second place, Hawaiian was 11% more efficient than the national average.

Researchers also noted in the study that shorter flights consume more fuel on a passenger-mile basis because of the large amount of fuel required for landing and takeoff, a key factor in Hawaiian’s interisland business model.

Airlines’ investments in technological advances like winglets and aircraft design explained about one-third of the efficiency variances between carriers, according to the study, while seating density, flight occupancy and operational practices such as single-engine taxiing also made significant impacts on fuel consumption.
