Does Just Transferring Miles Between UA/CO "link" the accounts?
Quick question cuz I notice ppl keep saying link your UA/CO accounts and I did last week transfer all my CO miles to my UA number for 3/3. Did that act of just transferring between the two "link" them. I'm just curious cuz I have both UA and CO metal flights in the future and was wondering if I need to change my CO flights from my CO number to my UA to get credit in the future.
Might seem like a noob question but i'm just curious if I have both CO and UA FF numbers how does the new UA on 3/3 know which one to use? Which will be my number to use after 3/3. The preview sites says the OP number will be your new MP number but I already have a MP number.
