May I know if I can earn KrisFlyer Miles and KrisFlyer Elite Miles when flying on Virgin Atlantic?

If so, how is the miles and elite miles awarded?

For example, from London to New York one way, the miles they state on their website is about 3,500 miles.

So do I earn 3,500 KrisFlyer Miles and KrisFlyer Elite Miles?

When booking the tickets, do we give the KrisFlyer membership number and it will automatically credit into the KrisFlyer account or there is a need to register for their Flying Club and have the miles credited inside before transferring it to KrisFlyer account?
