I agree. No one has been a fiercer advocate for Delta pilots doing Delta flying, and for only Delta pilots negotiating flying with Delta management than BB has. Sure, he's a bit divisive from a N/S perspective, and he often defends ALPA when doing so seems irrational, but those are not cardinal sins.

If he happens to be on FPL, why deny it?

I despise hidden agendas, which is why I detest guys who pretend to be something they are not, or who deny their affiliations.

I just want to know what general position, if any, he has in ALPA's hierarchy, in an attempt to better frame his perspective.
