If your upgrade hasn't confirmed by the time you leave for the airport, I usually ask to be put on the list when I check in. And then as soon as I arrive at the gate for the connecting upgraded flight, I **pleasantly** ask the gate agent if I am on the list...you'd be surprised at how often this gets messed up (i.e. DCA-DFW-HNL, with an upgrade DFW-HNL that doesn't get entered at check-in)</font>
One airport cannot place you on another's list...you have to be there and ask for it. There is no way to do this by phone or otherwise.
So, once the automatic upgrade time has passed you're on your own at each airport. It does put connecting pax at a distinct disAAdvantage as the others at your connecting airport will most likely get on the list ahead of you. That's when status really counts
