Scanned my card, with brief details of my flights in 2015, as well as my passport detail, and I got an upset answer: Welcome Miles&Smiles Turkish Airlines' advantageous Frequent Flyer Programme. 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 realised for extending your card validity date to 1 year, if 15.000 status miles accumulate at the end of the first year elite membership will extend 1 year more and the total validity date will be 2 years.
