Well, thanks to the schedule opening up, I've booked the first leg of my flight! I had planned on using Ding! fares for most of it, but I couldn't pass up a $90 flight from CMH - SAT with a couple-hour stop in HOU. Sure, I don't get an extra RR credit for it, but that's all right - it was cheap compared to some others I could have flown.

Let the trip-planning commence!
