12,200+ voluntary hours.

IMO there is no critical staffing issue until GSWC are handed out like candy. A350A last year, 717B summer 16, and NYC7ERB couple summers ago are great examples of true critical staffing.

This summer was just a spike of GS due to JFK runway construction and rolling thunderstorms thru multiple hubs on a near daily basis in July. Even with all that GSWC was not needed often
