We’re building a new technology system to integrate the MileagePlus & OnePass membership base. We’ll be changing MileagePlus numbers to 8 characters, so we encourage you, to link your MileagePlus & OnePass accounts if you have both, at http://united.com/linkmyaccounts. Current OnePass numbers will continue to work in the new system. Details are at www.mileageplusmergerupdates.com or www.onepassmergerupdates.com.
