A couple of quick points, but I argue neither way. It does not affect me, so I have no right.
If you argue that the 330 should get as much as the 777, shouldn't you also argue that the E190 should get the same as the 737? If not, pray tell, what is the difference in principle.
Not all VAI commuters get the assistance of positive space. There is also argument that commuting is not a right, but a privelege, and therefore should not be a part of an agreement (EBA).
And: Do you really want to commute domestically? Take it from one who has done a fair bit of it, even with positive space, it's a pain in the arse, it's expensive, and takes you away from home for considerably longer than being domiciled in your base. There is a big difference in commuting on a domestic roster and the five or six trips (56 day roster), on a long haul roster.
Be careful what you wish for.
