Hi folks

I’ve been Gold with Emirates for the last 4 years and never really bothered with Platinum as I, typically, only got to about 100k tier miles p.a. However, the last few months have seen some chunky travel that will take me to 147,500 tier miles for the 13 month period,
once I include a big trip next month.

Ive got a couple of Business Flex sectors booked from DXB - BNE and SIN - DXB that I could upgrade to F to try and bump the tier miles up. Does anyone know roughly how much the upgrade price from J Flex to F is? Or is there another way?!?
