According to United, ua1flyer is their #1 mileage earning flyer. Literally, meaning nobody has more BIS miles in the Mileage Plus program than him. Last I heard, we was somewhere around 9 million BIS miles and looking at 10 million by sometime next year. He apparently averages around 700,000+ miles per year, or me x11.
