Just wondering if anyone here has had any luck with a same day change to a flight leaving from a different airport. I'm scheduled to go out of BOS-PHL tonight, on a nearly full flight, but there is a PWM-PHL departing this evening that is showing Y9. I know origin changes are not part of the SDC policy, but has anyone had luck with an upgrade based on circumstances?

I'll make my BOS flight just fine, but I bet they'd clear some standbys if I left from PWM instead. And the two prior PWM flights also have seats, so we're not talking about a backlog of people to accommodate.
