I understand the disruption - but, assuming that every crew base costs money, it's imperative for management to figure out the least number of crew bases that the airline can reliably operate with. Blame the wizards at CCY for not taking a hard look at this issue earlier.
SBY, ROA, CHO, LGA, SYR, MDT, EWN bases are left. That's still seven bases for 55 aircraft. EWN is 220 miles from CLT and SBY is just 99 miles from PHF. According to an earlier post on this subject
here, CLT and PHF were closed because there were no overnighting aircraft at those locations.
America West had 150 planes and one pilot base. PDT had 55 planes and NINE crew bases. Do the math. This isn't the old US Airways.
