SFO is OK but other than the staff (who tie the LGW Arrivals staff as the absolute best in the US system) I really don't see what makes the SFO Club so much better than DCA, CLT, or PHL??? I've been there at least a dozen times so I don't think I'm missing anything.
I'm with Beckles > > >
the LGW Club is #1 in my book. It's as nice as any Club in the system and it has free booze and champers! ^
