230 AC on order, not including the 11/14 319 leases/options. If they get rid of all 747 (22), all 757(95), and 767(51), plus some of the leased 737-800/900(99), the pilot count could go down with 267 net AC loss. But if we assume only half go away that is 267/2=134ish. So a net of approximately 100 gained aircraft yields 1000-1500 more pilots. Probably peak of the bell curve of possibilities unless there is a 100 seat order, a merger, or a significant world event.

Nice day out though.
