I'm thinking about using same-day standby for an upcoming flight on Southwest Airlines. I would like to check a bag and am wondering how the timing works.
Southwest has a general rule that the earliest you can check a bag is four hours before departure. So let's say I am booked on a flight departing 8:00 PM, so normally I would have to wait until 4:00 PM to check my bags. Now let's say I want to standby for an earlier flight departing 1:00 PM.
Would being on the standby list for the 1:00 PM flight allow me to check my bag earlier, say anytime after 9:00 AM?
If not, do I just have to wait outside security with my baggage to see if I get cleared for the 1:00 PM flight? Will I have enough advance notification to check my bag and get through security in time to board?
Or is it only possible to use same-day standby with checked bags when the earlier flight is much closer in time to the original booked flight? (For instance, standing by for a 6:00 PM flight would be no problem.)
If it matters, this is a domestic US flight departing from Denver (DEN).
I'm aware that when traveling standby, there is a risk that my bags may not travel with me, and could be delayed. Assume I'm willing to take that risk.
