Hi all. I don’t fly SWA very often, and I don’t think I’ve ever done a flight like the one I just booked. It has a 45 minutes (on paper) layover in Denver, with no plane change.

How exactly does this work? Do you (can you) stay on the plane the whole time? If you get off, what boarding number do you use to get back on? If you stay, can you “upgrade” to a better seat after the non-continuing passengers deplane?
