With the recent American/USAirways merger, I am assuming last year's promotion for 50% bonus on airline mileage transfer from hotel points is a thing of the past? American does not appear to be a Marriott partner, therefore, that terrific bonus is obsolete, unless anyone has heard otherwise.
I loved taking advantage of this bonus promotion, but the only airline partner I see with a small bonus is United (offering a small percentage bonus, but nothing near 50%). Neither Marriott nor USAirways expressed knowledge of any plans to resurrect last year's bonus offer.
