Re: upgrading a domestic flight with miles.

The return flight cleared immediately and charged me 17,500 miles, which is correct as far as I know. However under "View Reservations" it says 17,000 miles + the dollar amount of the ticket.

The outbound cleared the short segment immediately and waitlisted me for the longer one. But immediately I got the "must be reticketed and call United" message. I called and someone worked on it for 10 min. Nothing changed at least from what I can see in view reservations. Will I really have to call and reticket after such a routine request?
