With our current PWA there is an arguement for no short call. Long call covers open trips 2 days prior and VAS covers any immediate need which is same day. I wouldn't be surprised if there's a shift eventually to these two forms of "reserve" (VAS can be a regular line add on) as the durability montra is driven home. Especially with known IROPS like snow storms and hurricanes. We execute very well outside of IROP disruptions and the focus is doing better when IROPs occur.
