I actually have enough miles to book the flight with them (legacy of flying out of Detroit for six years), but at this price (deep-discount V-fare on all segments) it doesn't make much sense. Better to save them for a later - hopefully more direct - flight. Departs at 7AM, but it wouldn't be the first time; it gets me there before registration opens on Thursday, and I'll have plenty of time to say goodbye on Monday with a 5:25PM return.
Fun fact: Spirit have just started flying to Pennsylvania from DFW; unfortunately, their flights land at an airport over an hour's drive from Pittsburgh. Add in a taxi and a train ride (if you can fit the schedule) and it's just not worth it. Was an interesting option to investigate, though.
Next up: Hotel room. Anyone got a slot free? (Thursday night-Monday morning, obviously. Not that picky about location.)
