True dat.. but they DO burn twice as much gas.. or more... and there is a point of diminishing returns. When those airplanes operating margin is what they want it to be, they get parked. There is a curve, and when it hits that curve, out they go. They will cut their losses rather than continue losing money (when the point to operate the aircraft becomes too great) regardless of how much they have invested in lie flats etc...
