But it's quite an unfair comment to compare the infrastructure for a 40 year old (fuel hog) compared to a brand new class of VLA, of which only 2 examples are in service yet!
True enough the Classics are a bit thirsty, but the -400's aren't.
They burn a little more than a 340-600 and are much faster, so I imagine the fuel burn per sector would not be a great deal more.
