I have an upcoming trip with United from SFO to PVG in a few weeks. I will depart at gate 93 at International Terminal, Concourse G, SFO .
The PP site indicates the following for the Air France KLM lounge: Flights departing from Concourse A only.
(1)Does that mean I can't access this PP lounge this time? I appreciate if someone can share his/her experience including the approximate date.
(2)If I can access it, how much time do I need to allow to walk between the lounge and gate 93? Do I have to pass security check again?

Thanks a lot.
