Also, B6 would be slightly larger in DC as well, with 4 or slot DCA slot pairs, and then assuming the LAX/SFO-IAD flights.

B6 would inherit the LGA and EWR slots from VX which is of value as well.

I think a B6/VX, as a merged entity, would have to be primarily focused on the coasts for major point of presence, but if one counts the actual domestic markets with a sizeable presence: LAX, SFO, DC, NYC, BOS, MCO and FLL, that is good diversification for the size of a B6/VX merged carrier.
