Hey all, so after some fudging with my schedule and many many flights, I will be in Japan a little later in the summer and while there I'll be dinging up from JGC Sapphire to JGC Premier. I'm wondering besides finally getting access to the F lounge in Narita for the flight back to the US, is there anything "new"I can experience that I wouldn't have being JGC for a decade now? I'm assuming it's still the same International security checkpoint that I've used as a JGC member for some time now.

Also, how "wowed" should I be by the F lounge over the regular Sakura lounge?
