JungleBus,

ATL, DTW, and NYC 717 F/O categories all had 79 ALV for June. My numbers would be 12.5 fewer REG lines across the 717 fleet. I suspect there aren't enough NYC LCP to handle this OE, which is why some NYC F/Os are training in ATL. The fewer REG line holders would occur in the base where the company pulls the OE trips. For June, here are the actual line counts. Using the TA language, we would have 13 fewer REG line holders among these categories:

ATL 198 REG, 63 RES
LAX 13 REG, 6 RES
NYC 76 REG, 26 RES
DTW 48 REG, 15 RES

I didn't see any LAX pilots in training in June.
