IMHO Virgin AU never flew to SFO, so no changes there......
Virgin America chose to make it's main hub in SFO and no hub in LAX; after less than 2 years in operation, it has built up a mini-hub at LAX and now V.Australia is stating that LAX is 1 of 2 strategic hubs -- and SFO is not. Part of that famous Virgin flexibility. Never mind that SFO has terminal and airport that is 10x better than LAX T3 (the most rundown and crowded of the LAX terminals, as it was expected to be torn down by 2010).
