I've been a Platinum Member for a while and now transitioned to Premier Platinum. Everytime I sign up for RewardsPlus it shows a different United MileagePlus number and have to call to change it. Is there anyway they can permanently keep my United number in their files so I don't have to keep on calling them? Also, I can't find the number on the RewardsPlus site anymore. Does anyone have it? Thanks in advance!
