Nashville International Airport (BNA) will probably be your best bet for price and location. www.nashintl.com
You might try Chattanooga. Think it would be closer than Nashville. It may depend on which NYC airport you choose, too.
They fly out of Laguardia, I thought of Asheville too, but it would probably be the same. I think they will just end up paying the $400 per ticket and go to Knoxville... The other places are too far. I guess that time of year is so busy so the prices are high. I thought if something were just as close, I could check prices but I have to go pick them up so I would rather keep it close :)
