I have heard from more than a few mainline pilots that I commute with that they indeed are concerned about and watching what's going on at the regionals. Besides not wanting weaklings in their ranks, they are also looking at what they perceive as ( and I tend to agree with them ) Parker's long term plan. Parker will drive the cost disparity between the mainline and it's regional feed so large, that it gives him the ammo he needs to go after mainline scope next. He will use that to threaten pay cuts at mainline in order to get them to give the 190's up to the regionals. Then what's next, Airbus? 737's? Forget flow. They will have you right where they want you. Flying mainline aircraft at the regionals, for regional pay, for the rest of your career. THAT is what mainline pilots are afraid of. And they should be.
