The near mythical free upgrade has just happened to my wife.
As I posted a few days ago I booked her a PE ticket using my miles for her to join me in NYC.
She was sat at the gate waiting for flight VS009 to board, when she was called to the desk. Apparently PE is overbooked, and they told her that as she is smartly dressed and traveling by herself that they would like to upgrade her to UC.
As you can imagine, she is delighted!
