i've been thinking this for a while and after seeing the uniforms it looks like it's happening:
* Uniforms look like Virgin Atlantic, even the oversize Ray Bans?
* If you look at the color scheme for Virgin Atlantic, look at the tail and compare
it to the missing area on the tail of the two mostly white AFL jets, to me it looks like the curve at the back is going to meet with a new Virgin Logo like Virgin Atlantic...
My long shot:
Singapore Airlines sells out of Virgin Atalntic, allowing Virgin Blue to trade as Virgin Pacific or Virgin Australia, Virgin Australia/Pacific aligns with Virgin Atlantic through Hong Kong and Virgin America through LA (already happening.) Virgin Pacific/ Australia Jets to look like Virgin Atlantic......
