Marriott - bizmile is "only" an update of points and/or miles-account problem. The general program informations on Marriott's homepages (programs, rules, promotions) are acceptable
UA's website is not only a mileage-update-problem (hopefully and promissed soon solved). UA's online-information is for the mileage-program poor, often uncomplete and months behind (years: mileage-plus-guide for US members dates back to summer 1997!, months: Ansett/Air NewZealand miles count as UA-status-miles since jan-1-99) or show up never (most bonus-miles promotions outside the US).
