I will be there around noon on the 25th, and my flight out is at 8pm on the 26th. If you see a slightly guilty, utterly happy, exhausted looking chica with a Canon camera and lanyard around her neck, it's probably me.
Go to Southwest.com and find the link that says "view or change your flight". Confirmation number and name, and you should be able to see it.
Or you could just look up the flights, like you're booking, on your dates, find the flight number, and see if anything's changed.
But I don't think that SW changes flights very often.

I started looking around for my lanyard (I collect, but do not trade, pins and only wear them at DLR) and AP, to put in my bag (I'm only taking carry-ons for this trip), all because of your thread. Felt like if I was doling out the advice I'd better ACT on some of it!
