TWO long haul round trips ex-HKG in J (and even Y for routes like YYZ, JFK) earns you over 30,000 miles, more than what you need to qualify for Silver. Say a traveller will be doing two of these round trips next year, one in April and another in November, however the tier resetting date is on October 1st, meaning that the miles earned on the first trip would've gone to waste by the time the 2nd trip is completed.

Can a quick call to MPC change the date of tier reset so that both trips can be counted towards the total mileage accrual and eventually passing the 30K mark to collect silver?
