Quick question. I'm a CM and UA Plat, purchased a fare to MVD on CM ticketed and paid to CM. I like the generous UG policy of CM. I may be short a few miles for UA 1K. If my PTY-LAX UG gets confirmed in advance at the 72 Hour Window, could I change my Connect Miles # to Mileage Plus and get credited to UA. I have heard and read conflicting stories. Has anyone have personal experience with this? Thanks and Safe Travels.. (And yes my L Fare credits 50% to UA).. Thanks and Safe Travels
