I'm wondering, considering the economic doldrums most airline companies seem to be in, why these planes are not put into use in lieu of buying new ones? The answer, I think, would depend on the difference in operating costs between new and older planes. Could someone with a better understanding of these issues shed some light on this? Solid numbers (eg. purchase prices of new vs. used planes, fuel consumption differences, etc.) would be highly appreciated.
