I have to wonder if Parker finally had the epiphany that in order to control your brand and product, it's much easier if you do all the flying, even under a WO.
If so, you'll slowly see additional aircraft shifted to the WO's as long as they can continue hiring and contractors going away as their contracts expire. AWAC may be the first casualty in 2018. Removing the 170's from Republic and gaining additional aircraft at Envoy is a sign things might be moving that direction.
