Honestly, I don't think a swap to ALPA is going to help you guys any. What Omni desperately needs is a unified pilot group that supports a strong EXCO. Right now, as far as I'm aware, Omni has neither. The EXCO can do what they can to rally you guys, but without you guys getting mad, flying the CBA, and electing an EXCO that's ready to get down to business, nothing will change. Leadership needs the support of the group; the group can't sit back and expect that paying dues is all that's required for a better CBA.
I absolutely wish you guys the best of luck, but you need to unify. The Teamsters aren't perfect, but it's what you have, and sitting back wishing you had ALPA won't do anything for anyone.
