As I indicated in my initial post we will be arriving from PVG on KA and connecting to CX to SFO on the 0130 a.m. departure (both in F class). I would like to visit the new Pier F Lounge. As someone indicated that the SFO flights usually depart from gates 1-4, will it be difficult to get to the Pier F lounge and then back to the gate for SFO ? Hopefully we will have many hours connecting time at HKG so would like to try the new lounge.
