Thanks for the help.

Yes indeed I meant CGK but as I research further it seems impossible to find CGK-NRT with an F cabin despite it being advertised on JAL's website.

I will be silver with about 900 TPs when I start the RTW in TLV. I'm hoping to end up with either 2,500 or 3,500 TPs in order to get the 2-4-1 vouchers although that's not my main objective. However, if a slight tweaking of the routing can get me over the next threshold then that makes sense. I think I have another 200-300 TPs of flying to do after the RTW but before my membership year expires.

I really want to maximise flights and length in F while trying a variety of F products rather than just BA. Besides that I really want to visit Tokyo and if I can Anchorage and my wife really wants to go to Vancouver and Melbourne.

It's hilarious how easily this escalates. It started with us planning one RTN trip in F and then realised that we could do a RTW in F for not much more. And it's become an obsession.
