I'm starting to get a strong sense of Deja Vu on this thread now, a lot of familiar names and opinions regarding VB. That said, I can't tell if individuals have really read closely what I initially posted or watched the video. So, I'm going to say again what most caught my eye about how DAL plans to implement this:

Once enough volunteers have come forward to make a VB workable in any given month, the flying for that month comes to the VB from their respective bases. That is, lines are built after folks have committed to the VB but before monthly bidding opens. So, the monthly bid packages could conceivably be built in such a way that seniority is honored if PBS can 'learn' to anticipate how folks are likely to bid. Example: PBS builds flying aimed to please the top ten lineholders living in base X, the next guy in base X has bid VB so PBS carves out some VB flying aimed at his seniority level, and so on all the way down the line. No, I don't think PBS can do this now and maybe it never will get it right (we are a fickle bunch indeed). But a few years ago I wasn't seeing ads on web pages that were customized specifically for me based on my prior web browsing history either. Darn cookies.

Anyways, the DAL VB threads had a lot of the exact same discussion as what has transpired here. If their test falls apart, and I can already see how it might, I'll be glad we didn't go there. But if it works and becomes routine, well, we'll have been handed some bargaining leverage at least.
