Look Guys, the Legacy Carriers simply can't exist without Regional Feed. Just as you've seen massive consolidation of Legacy Carriers, you will see massive consolidation of Regional and LCC.
I predict the Majors will once again want the full control of their feed and repurchase Regionals. Farming it out has proven disastrous to feed stability.
I also predict that once purchased that they will just give the now Wholly Owned Regional Pilots a Seniority Number because that will prevent the FO's from jumping around like a bunch of damn crickets. The Legacy Carriers require Regional Stability and they will have it.
