I went through the web form to request the miles from my ORD-IST flight on TK. The IST-ORD flight posted already. Denied.
Emailed MP customer service. Asked for more info. I sent the Receipt/Itinerary from TK, online check-in BP, and the new BP we were issued at the TK counter at ORD. Rejected.
Thank you for contacting MileagePlus Service Center again.
Your request for flight credit was rejected by the Star Alliance member carrier. It may take up to 15 days for this discrepancy to be corrected so that we can credit your MileagePlus account.
Thank you for your patience during this processing delay.
We're glad we could help. Don't hesitate to contact us again if there's anything else we can do.
What a pain. I'm not giving up just yet.
