You need to think very carefully about that sentiment before you stand behind it. Sit back, take a deep breath, and think to yourself, "I will take ground beef off someone else's family table to put prime rib on mine." If you're really, honestly ok with that line of thinking then you have no business in this profession. What do you hope to gain if Pinnacle leaves the Delta family? A few more airplanes?? A slightly better schedule?? An extra flight attendant in the back to stroke your ego??
I was in a position to watch the ASA pilots sit back for far too long before finally stepping up to the plate and fighting, really fighting, for a new contract. I was there, fighting for a better contract, long before you ever set foot on property, I'm guessing. I'm now in a position to watch (albeit from afar) the Pinnacle pilots step up to the same plate. So far, I'm far more impressed with the Pinnacle pilots' resolve than I ever was with the ASA pilots' resolve. They have organized faster, gotten pissed off faster, and taken things into their own hands to make a difference faster than the ASA pilot group ever did.
The Pinnacle pilots aren't your problem. Mother D is. Do you honestly want those 900s so badly that you're willing to see another union pilot lose his or her job? I sincerely hope that we, as a profession, are not at this point. If we are, then this "profession" is lost.
Believe it or not, we as pilots actually used to look after each other instead of fighting for scraps. Management didn't break us down, we self-destructed. Sadly, lots of people have gotten rich off that self-destruction and not one of them knows how to fly an ILS, land in a crosswind, or analyze the suitability of a contaminated runway for landing. So.... when you publicly advertise your desire for Pinnacle to lose their Delta contract, exactly whose "best interests" are you looking after? Your own or those of the people who continue to make money off your naiveite an inexperience with the true nature of this business?
I don't mean to be harsh, but a small dose of historical perspective would do you a world of good.
