Not quite true, KH. On my last MHD, I changed my departure flight from YEG to YYC, and again my YVR to YYZ trips. I have also just changed my final segment from today to July 1st. All my miles on the flights travelled thus far posted within 4-days of my completing the major portion of my MHD on Wednesday. Also, on both recent MHDs I changed the LAX-YVR flight at the airport to catch the 6:30 pm flight rather than the 8:30 pm one I was originally booked on.
