Apologies if this has been mentioned; I didn't find it on a search.
In November 2012, VX's CEO said the airline is working to add support for TSA Pre-Check:

Security
TSA hassles are the bane of business travelers who fly often enough to know what a joke our current “security” model is. The TSA has been moving toward a risk-based model that would allow frequent travelers to bypass many elements of the screening process. With recent changes to the TSA’s rules, Virgin is now eligible to participate in the TSA’s Pre Check program. Cush said the airline is working to modify its systems to enable its fliers to participate and hopes to have it available shortly after the holidays.
As a member of Global Entry, I would certainly be enticed to fly VX more often (versus United) if I knew I could get Pre-Check. It's just so much better.
ETA: In reading other news articles about the subject, other airlines are mentioned as being in talks to add Pre-Check, but not VX. So perhaps Pre-Check isn't happening anytime soon for VX, after all. Anyone have updated information?

Update 6/3/13 -- Pre-Check is NOW OPERATIONAL.
