However, if your flight is delayed, then you can stand by on any flights to any surrounding destinations (at least that was my experience). When I was a poor college student, I used to fly WN from Bay Area down to OC (OAK-SNA) a lot. There had been a few times where my flight was delayed for a couple of hours so I took the earlier flight to Ontario/Burbank/LAX instead. My parents weren't very happy having to drive longer but I got home earlier
