Just for grins, I did a random booking from Louisville (SDF) to Orlando (MCO). Dec 17-24 (I would have gone to January, but website would only let me select through December). Tickets were very cheap ($113 RT)
First, only one flight a day. But there was a flight each direction every day. (Hopefully) with "traditional" airlines, you won't have to wait 24 hours (if not longer if the flight is full) until the next flight.
Looking at bags... you're allowed a "laptop" carryon bag (that fits under the seat in front of you). Another carryon bag was $60 at the time of booking, and up to $79 at the counter. Unless I'm only doing a single overnight, I need more than my backpack. That's another $120. So $233 round trip.
For comparison, Delta (I get a free checked bag) is showing as $511 RT. Southwest (two free checked bags) depending on flight could be gotten for $305.
Is it worth it to save $70 -$250+ per passenger with the CHANCE if you miss your flight, have a weather or mechancial delay, the next flight is in 24 hours and everyone else will be trying to get on that flight also. I can see where it's tempting, but give me the traditional airlines anytime. AND, if I know I'm taking a trip, I can start stalking airfares months out.
