I do realize that the MD88/90 will be utilized until the end of the decade.
The question is with the non common types, does it cost more to operate the A332/3 spares, rotables, etc.
or can they be traded for 77L or 77W. This order obviously is aimed at domestic 150-180pax aircraft flying
under 2200nm. Most of the A319/20 and B752 early vintage (around 80-100 airplanes) And few early non
ETOPS 763 up in cycles.
Again newer A319/20 A332/3 B75/63/64 will soldier on and difficult to phase out until their useful life
is well utilized. The current CR7/9 E17/9 CRJ/ERJ fleet will take a while to convert to C-series.
I do not see DL replacing the B744 with another quad, it most likely will go the way of the 77W.
