You have to go back to the origin
...to the time this crop was planted.
Mainlines didn't want anything that didn't have "Boeing," "Douglas," and later "Airbus" stamped on it.
Give the puddle jumpers to the little kids to fly, we don't want them. From the fertile ground sprang the so-called "regionals." Had the big kids wanted to play with the little kids' toys, they would all be on the mainline property and the scum sucking, bottom feeding, bar lowering b-scalers such as Comair, ASA, ALG, PDT, SKW, CHQ, etc, etc, WOULD NEVER HAVE EVEN EXISTED.
Yup, you big kids scored a major victory, there. Your stand on the segregation of real pilots from commuter pilots created the feeding frenzy (or whipsaw, the terms are interchangeable) that threatens everyone's way of life and sits like an anvil on the so-called bar. You have to go way back; way, way back- back to when Metroliners were still new and Jetstreams were not yet on the drawing board and follow the consistent refusal of the mainlines to allow little airplanes in.
Well there was a market and it should come as no surprise to anyone that companies sprang up who were willing to fill the need. This monster is of your creation and now it is out of your, and everyone on the labor side of the table's control. Now you lament the results: everyone, including the mainlines are fighting like starved jackals amongst each other and amongst themselves when the very work groups who are fighting with each other and with you are the product of your own disdain for the work you now covet.
This isn't about competition with Jet Blue, it's about reaping the fruits of segregationist mindsets that date back to before many of the JB pilots were even born. The foundation for today's airline world were laid back when commuters were emerging from the primordial ooze of navajos and cessna 402's. Had the mainlines had a little more forethought and a little less pride, none of this bitter harvest, NONE, would have ever had the chance to be conceived, much less harvested.
