<p>I rarely fly SW, but if I were going A to B to C, and then C to B to A, yeah, you could easily get off the return flight at B and walk away. Nothing will happen and they won’t cancel the B to A plane for other passengers. I’ve done this multiple times flying internationally where I just grab my bags at my port of entry in the US and walk out instead of rechecking thm domestically. People miss flights all the time and they don’t hold or cancel planes. I wouldn’t get the upgrades I do if people weren’t missing flights.</p>
