It clears segment by segment. And it is burned if it clears on either segment. If JFK-LAX is not available for upgrade at booking, you should call and ask the agent to apply it only to JFK-LAX, not the LAX-LAS segment. Then if the transcon clears, you can ask to have the RPU applied to the LAS segment as well. Otherwise you may burn the RPU and only receive an upgrade LAX-LAS.
