Haha, it's weird how the times have changed. You could fly cheaper, if you are stopping for hotels and meals.
I know. It's been that way for the last 12-20 years. When I lived in California, I could always get a round trip ticket into Nashville for around $150. Much cheaper than flying into TYS. Could rent a car in Nashville for a few hundred and still saved money. Used to be able to catch a flight from Dallas to Las Vegas, back then, for $30 round trip. I checked a round trip flight from here to Knoxville last week and it's still cheaper than driving counting gas, meals and motels. Stupid.
