I know this idea is well intentioned but it has to be one of the most poorly thought out things I've heard on here in a long time.

Let's assume you are able to get this organized or not even organized, but enough people do it. Let's be honest, enough people are going to have to do it for this to have enough effect to a) have mainline take back flying or b) have regionals offer better benefits. By the way, a regional isn't really even capable of offering significantly better compensation without taking it from somewhere else. Their current contracts were bid with certain labor costs already accounted for. If you think, out of the blue, regionals are going to be able to just start offering 7 year pay during year 1, you're completely dellusional to the economic reality of the situation.

Scenario 1: Everyone quits. Flights are canceled and mainline picks up a big chunk of flying. Then you go to interview: "excuse me sir, might I ask why you quit X regional airline 2 years ago along with hundreds of your peers?" How do you answer that question? Even if you have a creative answer, you are going to be less likely to be hired at the now expanding majors because you have cost your "future" employer a LOT of money. Why should they believe you aren't going to do something like that again? It doesn't take a rocket scientist to know that you quit during the "great regional exodus." They don't have to tell you why you weren't hired.

Scenario 2: You quit and regionals significantly increase compensation and bonuses to new hires. Many of those regionals are going to go bankrupt and you have just screwed over everyone year 8 and above. Those that survive? Why should they rehire you? You, legally in poor faith, caused them to lose MILLIONS of dollars. I know if I was a regional manager, I wouldn't hire you back. I know your argument is that the companies aren't currently acting in good faith. If that were true, a federal mediator would be able to determine that and the pilot group would be permitted to strike. At this point, it hasn't been determined that this is, in fact, the case (legally).

So, let's say you jump ship and things DON'T change. Now what? What do I do now? I haven't been making enough over the last x years to have any significant savings accumulation. I might have student loans or a family to think of. Where are 1000 ex-pilots going to find work? The economy isn't that healthy that you can just go find a decent job somewhere at the drop of a hat. Many people have given up the left seat (many regionals are well within 5 years for upgrade) for this harebrained idea and are now competing with would-be fresh ATPs for a chance to be at the bottom of the totem again.
