May I suggest that if you find yourself in the unfortunate position of being denied access to a jumpseat in this battle, that you consider yourself an unfortunate but necessary collateral damage casualty in a much bigger and more important jihad?
For many inconvenient political snares, ALPA may choose not to fight this war in a traditional manor. Alternatively, the mainline pilots full well know the "camel’s nose under the tent precedent", that this scope violation sets. Without stronger NATIONAL union leadership however, the only tool the line pilot has, is to create a situation that management has to deal with. Want to see management second guess themselves? Those nasty people that comprise those finger pointing delay meetings, make some real uncomfortable situations for your chief pilots who ultimately will have to give an account as to why all the feeder flights that violate scope seem to push late.
