Do UGs have to be re-ticketed by a phone agent like they do on DL?
They can be used on short haul int'l but not to Europe, Asia, etc. From coach to first you're looking for X availability, and from coach to business R. From aa.com...
Upgrades may be used on American Airlines, American Eagle or AmericanConnection marketed and operated flights offering a First or Business Class cabin within and between the 50 United States, Canada, Mexico, the Caribbean, The Bahamas, Bermuda, as well as between the United States and Central America (Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua or Panama).
For miles/copay, you're not charged the copay until the upgrade clears. These are reticketed, but an upgrade using 500mi'ers are not.
