Virgin and other carriers wont realise which exact aircraft is due to operate the route untill get to the gate. They do this for security reasons.
So you can ask which EXACT aircraft is operating a route once the flight is airborn ONLY.
Hope this helps!!

That's not strictly true as you can generally get the registration from a good few hours before the flight. If the aircraft is known and is specific to a return leg then I have seen this info supplied from the moment the outbound flight is airborne (so up to 11 hours ahead) - But this is NOT always the case.
For example: Todays flight to BOS leaving at 14:30 (2.5 hours away) will be G-VBIG
I had a feeling it was more a question (from the OP) about HOW VS decide. Why choose that aircraft over another, how does rotation work... The answers to which I don't know.
