So Virgin America announced today that they are opening SEA-SFO, LAX..

Does this mean it pushes out B6's future possibility of expansion of up and down the west coast out the door?...B6 could still expand west coast, but with Virgin now in the game, i think it's going to be harder especially here in SEA with now AS, WN, UA, and VX vying for that market share between these highly popular in demand routes.

Any thoughts?
