Currently sitting at ~74,000 FOP (~34,000 on JAL)...I am going to hit Diamond via a mileage run on the last day of the year, just in time.
Bunch of BA flights coming up + JFK->NRT in JAL J, which gets me to JGC Premier & ~94,000 FOP...then ITM-HND-OKA-HND-ITM to get me over the line.
Just in the nick of time!
Welcome to Diamond, and lets meet up in a lounge (hopefully NRT international lounge) sometime in the coming few months.
FYI, I am leaning on getting the 60,000 eJAL points as my choice selection (I don't have immediate family that needs Diamond status, and dont need the JAL coupons).
Keep us posted on your epic run at the end of the year.
