Had an exchange over 20days, They needed id, passport, status card, flight record of two month, screenshots of the dashboard and still I got denied. The reason I‘ve been told was that on the flying blue status card is no sky team elite plus logo and therefore the can‘t match me. Honestly I even tried with a friend of mine that speaks turkish, to tell them that the status I have is equivalent and easy too look up. Seems like turkish don‘t want too match from flying blue anymore.
