All in all, a great post.
I'd just add that, by design, PDT and PSA do not make any money. They are an expense on the Airways books are viewed as a way to bring people to the hubs so they can get on a mainline flight. They operate at cost without a profit margin.
That is pretty much what I was trying to say. WO's are operated at cost, but contract carriers are "cost-plus." They are- have to be- more expensive in the long run.
I don't think it was a brand/livery thing that got the camel's nose in the ol' tent, it was mainline's snubbing of the regional jets -- "regional" jets that now fly half-way across the country. If oils had stayed above $100, I think we would have seen a resurrection of the truely regional aircraft -- the turboprop. However, now that it's back down, who knows...but I'm not optimistic.
You are not going back far enough. Regional jets would probably not have even existed-at least in the numbers that they do- had ALPA never given any scope relief historically. It all began with that Henson (coincidentally!) Queen Air flying for Allegheney way back when. Once some scope relief was given, management was able to use that as a pry bar to gain further scope concessions from the mainline unions. First it was a Queen Air... Then 19 seaters, then 31 seats, then 37, then 50, then 68 seat ATRs. Then the jump was made to jets, the first RJ being concieved was put on the drawing board with 31 seats! It didn't take long to get to 50 and now we have 90 seat jets (basically 717s or mothership Fokkers!) flying around with pilots paid less than 40% of what they should be. My point is that it all began with that first instance of scope relief and ALPA was absolutely complicit in the fall of the profession. To this day I heap ashes on thier heads and say shame on them!
Finally, how would seniority list work with places that have crews moving between the differnet carriers
That is the rub, isn't it. If no scope relief had ever been granted than this wouldn't be an issue, but now everyone would be stepping all over each other for a piece of the pie. As I think I have demonstrated, ALL flying is and should be mainline flying and we are essentially "stealing" it and stealing from ourselves what could have been a better job. No honor among thieves...
