Has nothing to do with anything external. It has to do with the constant need to keep up with ROIC. As our fleets age (increased MX costs and eventual need to replace older airframes), as our labor ages (in terms of YOS--each year up to 12 you get longevity pay increases), the costs to run the airline will increase.........in order to keep up with what Wall Street expects, based on what the leadership at JB has projected, our current forecast of fleet purchases will not be enough to keep up with these expectations.....not even close.....
