"quasi-redeye that departs LAS at 1:30am (LAS) and arrives in DAL at 6:10am"

for a 1067 mile flight...

Sounds like an awful, dart board-ish, flight to me. But I guess we'll see.

edit to add:

The rest of the schedule does not look too bad, especially the DAL-LAS timings. I guess it make more sense than Austin...
