Hello,

This post to give an information that may interest people here.

I've matched my Flying Blue Gold status on last July and I have now a TAP Gold status (and btw a Star Alliance Gold status).

I was not sure about the conditions to fill to renew this one in next July, so I wrote to TAP Gold support.

The answer on my question is the following:
--
(...)it is necessary the accumulation of the 50.000 status miles or 40 segments of flights operated by TAP Air Portugal.(...)
--
You can note that it is "or" and not "and"
And for the 50 000 miles, it is status miles from TAP (easier) or status miles generated by flights on others Star Alliance Airlines (depending on booking class, the TAP website gives all indication about the ones that allow miles accumulation or not)

Hope this can help!
