Probably the same way I went from 280,000 miles to 2MM+ in under two years...signing up for every promo, mileage running, iDining and prodigious use of AAdvantage and SPG credit cards. I was also helped along by close to 700,000 miles worth of the finest shelf-stable swiss cheese money could buy...all of which (save one wedge) was consumed via a very grateful food pantry.
