VS 'R' Class Fares?

Am looking at prices for a possible UC trip to St Lucia in July 2010 and strangely the best rates are coming up with Z outbound and R inbound - anyone any idea what an 'R' class fare is? I have checked the guide on here but unless VS have bought Concorde on the quiet I am none the wiser [?]

The R fare code is a new code that VS started using last year. It is an UC fare, that is priced between Z and D, it does not qualify for a CDC and is pretty much restricted like a Z fare is.

Thanks for that Neil - had never come across that fare code on VS before.
