Turkish Airlines just matched my British Airways Gold status. Sent an initial request in using www.turkishairlines.com/en-us/any-questions/customer-relations/index.html
<br /> <br /> Once making the initial request, I received an email that stated: "In order to evaluate your request, we would like you to send the copy of your ID/Passport, the picture or copy of your Gold membership card's front side together with card statement that shows flight activities up to last two months to Customer Contact Center by creating a file via the link below: <br /> www.turkishairlines.com/en-us/any-questions/customer-relations/index.html
<br /> <br /> After about 1 week after submitting my documents, I received: "Welcome to Miles&Smiles Turkish Airlines' advantageous Frequent Flyer Program. Elite card trial period will be valid for 4 months. As of start date of elite membership within 4 months trial period one international Turkish Airlines flight should be realized for extending your card validity date to 1 year, if 15.000 status miles accumulated from Turkish Airlines international flights at the end of the first year elite membership will extend 1 year more and the total validity date will be 2 years. There is an opportunity to earn extra %50 status miles from your first business class flight in the trial period."<br /> <br /> Elite status now shows in my account. Very satisfied with the process.
