I am a OWE flying LAX-SFO-LHR soon with a 60min connection in SFO. It's my first time connecting in SFO so I would appreciate your insights on this.

LAX-SFO with AA and SFO-LHR with BA. My luggage will be checked through to my final destination already and I should be able to receive my boarding pass for the SFO-LHR leg in LAX already.

Is there any way to connect from Terminal 2 to the international gates without going landside? Is it likely to make that connection if flights are on time? How will the lines at 7:30pm at security usually be?
