I have a SIN trip coming up with an immediate turnaround( ORD-HKG-SIN-HKG-ORD ). For the SIN-HKG leg there is a message "Ineligible to accrue mileage or Premier qualifying credit." What's that all about? FWIW, I called the 1K line and the answer was "not to worry, credit would be given". Many times the United GPS would read things wrong, "happens all the time"
