We Know You Have a Favorite Airline

Flying has its environmental cost, but you don’t have to forgo your environmental sensibilities -- or the fun of travel altogether -- to maintain some sense of ecological righteousness. Ranking 15 major airlines, the International Council on Clean Transportation found whopping differences in the fuel efficiency of carriers, even among those flying identical routes. The most efficient airline overall, based on 2010 data, was Alaska Airlines; the least efficient, Allegiant. Alaska was 26 percentage points more efficient than Allegiant. http://sierraclub.typepad.com/sierradaily/2013/09/we-know-you-have-a-choice-in-airlines.html?utm_source=insider&utm_medium=email&utm_campaign=newsletter Article courtesy of Sierra Club newsletter by Reed McManus
