I took a roundtrip on CM between MEX and PTY last month and my miles have not yet posted. CM's FF program is MP (formerly OP). The MP rep told me I had to send in copies of my boarding passes and itinerary showing my CM ticket number in order to get the flight credits. I realize that when traveling on partner flights, this would be the protocol, but this doesn't make full sense to me in this case given that CM's own FF program is MP. Do I need to the old practice of calling back and speaking to another MP agent, or is this par for the course for flights on CM?

Thanks
