China Airlines Status Match

It's a "Corporate Extra" program, you can use the Cathy Pacific/EVA AIR diamond card to apply a superior card that equivalent to China airline Emerald, but it can only used on the flight which operate by CAL or MDA. You can also use the Cathy Pacific Gold or EVA AIR Silver to get a precious card that equivalent to China airline Gold.

Offered a superior card but not sure if it is equivalent to Skyteam Gold.

I contacted China Airlines directly through the Contact Us / Feedback form on the website. It's not really intended for this kind of enquiry, but they acknowledge my request via email after a few days. I requested Qantas Platinum to China Airlines Paragon (go hard or go home). After about 3 weeks, I just received confirmation of Superior level, which they tell me is equivalent to Gold (2 levels below what I requested). Proof of current Qantas card was required; they accepted a screenshot from my Qantas app.

email them and provide requested data
