I am quite confused with regards to V ticket rules.

I once was able to book a V class ticket courtesy of Marco Polo, but my travel agent can't issue it.

I was also told V class ticket requires a minimum of 2 people traveling.

I get the impression that some travelers are able to fly on a v class ticket alone. The lowest class ticket I've been able to fly solo in are L class tickets.

Would someone help clarify the v-class ticket requirement for me? Would I even be able to fly on a V class ticket solo?
