ZW is safe. They wouldn't buy 9E. They'd get nothing but pilots whom would all get a substantial raise. SKW got the first of 9E -200s on OCT 22. Tail 8903A. Endeavor currently has staffing for about 40 of them. They have about 85 left. Doesn't seem too hard to liquidate 45 shells.
Bottom line with all this shell shuffling, no new entry level pilots, there won't be pilots staffing any regional jets real soon. I think the vast majority of regionals will very soon not be able to staff their planes. Namely PSA.
