SFO airport

Does anyone know how crowded the security line at SFO airport near 11-midnight time frame. We will flight out by Japan airline at 1:00am . If we arrive the airport by 11pm and plan to stop by Centurion lounge, will we have enough time to go thru security again.

I do not know which gate Japan airline will depart. However, I know that Centurion lounge is in terminal 3 and our flight depart in International terminal.

We can arrive to SFO early 8pm -9pm, but the problem is our luggage . Japan airline counter only open 3 hrs before flight. Not sure the best way to deal with our luggage . I heard good thing about this lounge and want to stop by and use the lounge if we can for this coming flight

If anyone have use this lounge before your international flight, please advise. Thank you

The security lines tend to be long at that time because there are fewer security lines open (fewer personnel). If you have pre-check, the line can be faster if you get through before that line closes. I would recommend getting there earlier if you want time to enjoy the lounge. It's about a 5-10 minute brisk walk between terminal 3 and the international terminal.

I'm not sure at that time, but I was there at 0500 this morning and the security line on T2 was 2 or 3 people deep.
