Check 2013 MP Statements
I found a segment of a partner flight (SN) from June that did not credit mileage and it should have. Previous online submissions did not work. I wrote an email to MP and got a favorable reply - the 3k miles put me at 101,211. My first 1K status! My advice: check your MP statements to make sure all qualifying flights are included. Do a manual follow-up (maybe more than once) to request credit. I have several International trips scheduled in 2014 - looking forward to trying the GPU.
