V-Flyer

I've a flight coming up in a few days and the Retreat Suite is still showing as available on the seat map. Is there ever a world in which Virgin do a comp upgrade to it if no one buys it, or do they just leave it empty?

They remain un-occupied. Both times I've paid to upgrade, the other seat remained empty. VS did say originally they *may* offer comp upgrades to FF'ers with high status - this still remains to be seen though.
