Additionally, it is important to notice that when properly coded, a phantom/duplicate segment is shown in your itinerary where you cannot select a seat because it is showing you on the wait list. If that phantom segment does not show on-line, your RUC/GUC has likely not been properly coded onto your itinerary.
