I booked a flight from EWR-LAS via corprate travel through AMEX. My outbound flight was a W fare and was showing up as 50% EQM in my reservation. I knew about this and was really annoyed since the flight is tomorrow and with DEQM if it was at 100% with my return flight would make me gold by like ~80 miles. Unfortunately there was nothing I could do about this while booking since I had to book the cheapest flight. Anyway I just received my first ever EUA email about an hour ago. While it made me very happy it also really surprised me because I am now seeing my reservation show that my flight tomorrow earns 100% EQM. I think I read in the FAQ somewhere that after being upgraded you keep the same miles as the originally booked ticket. Anyone know for sure?

Thanks
