As yet another outsider looking in, I have a suggestion...
ALPA (for that matter - ALL of the pilot labor groups) need to go on a MASSIVE marketing blitz.
I talk to a lot of my fellow business travelers. Many of them have zero clue that they're a) flying on a regional jet b) that the crew's QoL/Pay are what they are and c) are generally shocked when I tell them what the crews are generally paid for the schedules they work, even beyond first-year pay. I've been a heavy frequent flyer for 15 years, but I only learned about this stuff since coming to JC almost two years ago.
To the man, they have all said, (and I'm paraphrasing) "Wow, that sucks!
I don't want a pilot paid so little flying me and my family!" There, I think, is your weapon. People are conditioned to believe that you guys are overpaid button-pushers who jet off to Paris on the weekends and shack up with 3 FAs at a time on your overnights.
But get the people paying the bills on your side, and management is going to pay more attention (and, potentially, money) if the public realizes the state of y'all's situation. They simply do not know, and they need to.
At the very least, it might garner you some public support the next time you have to hit the picket line.
Might even cut down on the SJS a bit.
Could also contribute to FAA revisions to raise the minimums for 121 flying as well.
Just my .02 as a
very regular customer of the services you guys provide. Matter of fact, I'm writing this in an airport right now.
