RPU cannot be applied until the itinerary has ticketed. You can apply the RPU online as soon as the itinerary tickets. Just go to "view reservation."
Or you just tell the phone agent you want to purchase the ticket and upgrade it with an RPU. The good ones can hold the R space until it has ticketed.
