My question is specific to UDU. If you get a UDU after you checked in but don't know it, what happens at the gate when they scan your coach boarding pass?

USUALLY it beeps at you, they will look at your seat, and they will just give you the new BP. Sometimes, you will board and they will issue a new BP after you board (this is the case when you earn an upgrade after gate closes). However, some overloaded GAs (esp during IIROPS) or inattentive GAs will overlook this and send you on your merry way. Only happened to me once though so its a common thing.
