My JAL status is Global Club only now. But it was matched with Flying Blue Gold for 12 months through statusmatch.com by paying $299 as fee.

I was required to submit Japanese ID. It seems there is a regional restriction for the status match at this moment.
It took 3 business days (5 days including Saturday and Sunday) to show the Gold status in my App after the approval of match.
