Well there is some good news...we live in Louisville, but have made the trek to Indy numerous times to save $$$ on trips to MCO....I always figured it was cheaper out of Indy because there was dicount airline competition out of Indy (ATA, AirTran) and only SW and the legacy carriers out of Louisville.
Now that SW and ATA code share the Indy prices are pretty much stuck at $145 give or take a little....while Independence Air, AA and SW are running specials for $120RT out of Louisville through May, and Delta, NWA, etc are running $144 through mid september....we are going in early November so I have high hopes that we may snag a $120+ fare from here for a change....sure would be nice to skip the trip to Indy (that airport is a dump!!)
Most of my family is in Nashville and they fly RT for under $100 on SW specials (and Delta and AA usually match SW)....so every now and then when we have time to spend a night there on the way back we will fly out of there....but I would be REALLY happy to pay less than $150RT out of Louisville and avoid driving either place.
