Well...I had booked Southwest out of Nashville to MCO for $95 pp round-trip, then Delta went on sale the next day from Huntsville to MCO for $156 pp.
I ended up booking Delta, too. It's definitely worth the extra $50 pp to me to save driving time. Nashville is three hours from the concert DH will be working at until midnight the night before we fly out, and Huntsville is only 1 1/2. Not to mention we can stay with friends the night before we fly out of Huntsville and leave our car at their house, as opposed to getting a hotel room in Nashville and paying for a week's worth of parking. That would have probably eaten up the money we saved on the Southwest tickets.
So, overall, I'm pretty happy with my Delta tickets. Plus I can use the SW credit until next year!
