*New* AirTran Boeing B737-200s? FL isn't buying any more B737-200s. They've got three left, and they only do PFL-MCO, ATL-MCO, and (I believe) ATL-PHL. Those B737s will be gone shortly.
I know several people who've flown them when they did JAX-ATL runs, and they say that FL has really stopped investing in them. Clean interiors, and no duct tape on seats or bulkheads, but clearly old planes waiting to be put out to pasture.
