Not for Major U.S. airlines... EVERY Major/Legacy CBA has a restriction against pilots flying company planes and not being on the seniority list.
I'm more concerned about the relaxation in cabotage, that is, allowing point-to-point flying inside the CONUS by foreign airlines. We give that one up and we're screwed. Trans-con flights connecting to Int'l flights and the bread and butter of our airlines is GONE.
That's been under attack for a long, long time. We all need to contribute to your PAC (ALPA-PAC or CAPA-PAC) in anticipation for the upcoming battle as retirements eclipse pilot availability at the Regionals to make sure the eventual Congressional and Senatorial hearings on the issue VERY CLEARLY point out that it's not, and never will be, a shortage at the Major level, but rather the minimum-wage paying Regional jobs and that the majority of feed amongst our larger cities will go on as-scheduled and without impact.
There's just not going to be a shortage at our level but yes, I expect things to get really, really tight at the Regionals starting around 2018-2020. Assuming the world doesn't end in 31 days.
