Matched in 17 hours
I emailed my request yesterday around noon, including a scan of my AA Executive Platinum card and a PDF of my AA account statement. I also explained that I travel to Turkey at least once a year and have enjoyed my experiences flying TK.
I received an email at 4:30 this morning telling me that an Elite Card status match has been provided. When I checked my account, I saw that the status is good through July 31, 2014.
From now on, I will credit all my *A flights to TK.
