I submitted a mileage upgrade request subject to waitlist. However, I am not one of the three names on the current upgrade waitlist when using the flight status link. In the past, I have both been told I had to be added by the gate agent and other times, that I was already on it even though it did not show.

Has anyone experienced this before? Should a waitlisted Mileage upgrade request show on the regular waitlist (I wasn't aware the UG waitlist would even show until 24 hours prior)?

Thanks!
