It is a windfall. Having a one-way fence where Colgan is protected to 193 CA seats on the Q and no XJ/9E can bid those, meanwhile Colgan Q CAs can bid to the RJs and keep reducing their quota number of 193 as they come off the Q400 onto jets. If this cycle continued and the Qs stuck around, you'd have a constant flow where current Q Captains at Colgan bid over to the jets, and they could only be replaced by Colgan FOs because the quota of 193 wouldn't be met.
That's a windfall, pure and simple. A one-way fence for no reason. And it wasn't a good presentation by the Colgan committee, it was the 9E committee that completely f'ed up and Bloch punished the 9E group by keeping them off the Qs AND the Saabs, since 9E pretended like all the Saabs didn't exist. Idiots.
