It's actually a
written rule. I'm sure that some RES or TA agents aren't aware of it...but, it does exist. Suggest they look it up internally. You need to show up at the airport or call within one hour of the flight departure. If the same booking class is available on the next flight you can SDC with fee waived. If class isn't available...standby...with priority C for the flight. After the last flight of the night...you get the first flight of the next day hopefully confirmed in your booking class or standby. (I've heard that some agents will just book you in whatever class to get you on your way...
.YMMV.)
