American belongs to One World (along with others)
Each has international choices and partners also!
I'll second
jessej's suggestion - when you fly a partner in the alliance, credit the miles to the one you have. Example: when you fly CO, credit the miles to DL. Or when you fly US, credit the miles to UA.
If a Star Alliance award is 50K, but you have 40K with UA and 15K with US, you do not have enough.
(You can not combine accounts for awards!)
But, if you had credited those US flights to UA, you would have had 55K in your UA account, and had enough for the award!
