For anyone interested, Turkish are offering a status match to Gold members of Star Alliance, OneWorld (Emerald) and Skyteam (Elite).
This link will take you to their customer site,
Just click in and follow the process. I think you may have to join the programme first (I was already in).
You’ll need to upload a copy of your current Gold card and a copy of a couple of months statements. I just took a screen print of my online account.
