It is true that total cost (ABX vs. ATI) are relatively the same. Also that the differences in where monies were applied at ABX without home basing were in total work days and retirement. Did we get the right value? Argumentative discussion at best.
Operationally speaking, for now ABX has been able to work out pairings with minimal DH on company a/c (on occasion limited positioning commercially) as indicated by Reactivity. The challenge is ensuring ABX has city pairs and schedules that continue to make it work. So far, being limited to 6 -200 aircraft makes the task simpler. I can see where ATI has more point-to-point (no transit CVG/ILN) destinations and that option make not work easily.
I have forecasted it before and continue to state...unless there is a shift in temperature with AMZ, that ABX will be out of the AMZ account upon the termination (or cycle out) of the six aircraft we operate for them.
