As usual, you are wrong but I'd love to hear the contorted explanation of how the higher cost group would get the new flying.....

Jim,
Management, within rather wide limits, can assign costs to whichever part of the operation they wish. They can (and do) rinse, lather, and repeat the numbers with a surprising amount of latitude.
It is the yield that is important. If the yield for a given investment is higher in the east than the west, assuming sane management, that is where the investment will go.
Disclaimer: I make no claims as to the sanity of Tempe.
