Hi,

So I have flown Virgin Atlantic, and now having moved to the US will be flying virgin america SFO-NYC

My question to the esteemed forum members -
- Should I treat those two as completely separate airlines, or does it make sense to try and accrue points on one or the other?
- Do they even let you register an FF# from the other company in one airline?

Thanks for demystifying this!
