Freighter Reserve Coverage?
So, checking the roster for 747 freighter captains in November there are in
ATL 5 R days out of 4 CN (5/120 man-days)
ORD 6 R days out of 3 CN (6/90 man-days)
JFK 4 R days out of 3 CN (4/90 man-days)
LAX 0 R days out of 4 CN (0/120 man-days)
Total 15 R days total for 14 captains
15 R days out of 420 man-days
I guess they're counting on G day workers.
