To clarify your quote of my post, I was writing about the quality of the Clubhouse together with the overall service quality in Y of VX and not popularity of the Clubhouse and that AS should be worried. "I was the only pax in the Clubhouse" is a separate issue. Entrance into the VS Clubhouse is still highly restricted if you are a VS pax, however, you can buy a pass if you are a VX pax, regardless of class of service.
Note that I got to the VS Clubhouse AFTER VS FC passengers boarded their flight to LHR. Secondly, a VX flight to SEA had already departed. So therefore, the VS Clubhouse emptied out when I got there, FYI.
