As we should know, DL has ordered 100 737-900ERs (okay, not technically yet, but 99% likely), I wonder, what will happen to DL's older 752s that are eqiupped with AVOD? An example of one of these aircraft is N610DL (the former Pink BCRF 757).
I surely hope DL orders their 739ERs with AVOD, however, DL has some younger 757s that lack AVOD, such as the 5600-series ex-NWA aircraft. I personally think a good idea to save some money vs. buying completely new AVOD systems would be to transplant the existing seats/AVOD onto younger 757s that lack the system.
Also, DL was planning to replace the overhead CRTs with LCDs on the PMDL domestic 752 fleet. Is that still being planned?
