I work as domestic crew for Virgin and I doubt they will add more destinations in the near future as V are still losing money. They are relying on the tie up with Etihad to make some serious $$ to the bottom line. They are also looking for an Asian partner to tie up with as well so if you join now, you will most likely be doing LA and Abu Dhabi for some time, which are both around 14 hour flights, plus add on a few more hours for sign on, sign off and transport times. I heard from a friend who's partner is at V that the hotel in Abu Dhabi is over two hours away and it's a similar transport time with the hotel in LA.
