I am not too familiar with DL's confirmed changes. With CO, $25 confirmed standby will get you a guaranteed seat when you call within 3 hours of your desired flight (not within 3 hours of your originally ticketed flight). They cannot do confirmed standby >3 hours prior to departure of your desired flight.
Standby at the airport is free, so if the flight is wide-open (e.g. 753 that's only 70% filled) you can take a chance. Of course, if you must be on the flight, then $25 will cover you.
Good luck.
