It's was a wonderful piece of reporting this week in the Middle Seat column of the Wall Street Journal: a review of DOT data, yielding what amounts to an MPG rating for the airlines. Alaska came out on top, with a bit of luck (like being West Coast-based) and some good practices (like shutting down engines quickly at the gate). The worst guzzlers turn out to the three biggest U.S. carriers.
But here's the big question: would information like this -- that getting you from LAX to JFK sucks around 10 gallons more fuel on Delta than it does on JetBlue on average -- cause you to change who you buy your ticket from? Let us know in the comments.
