Considering this forum is one OMG moment after another and 99% never happen I would say the forum is FUD after FUD from the usual suspects.
If what this forum posted about contract 2012 had turned out to be even remotely true you would not even have a job here. Just a couple of other examples include 20 pages of the evils of augmented domestic flights and the disaster that would be and 20 more pages on all the two man flights FAR117 would be causing. How did those turn out.
The simple fact is the domestic system is fairly low credit. A VB only makes sense if you can reduce that credit further and not increase your greenslips at the hubs when irregular ops hit.
In the end we can simply do nothing and the entire program dies. If we want to extend it we can via LOA. That LOA can take any form we want including extending the right to pull it down at any time. The company will have zero leverage so they will have to accept what we want.
As I originally posted the entire VB concept is so watered down from what the company really wanted as to now have very limited use.
