Question: how much are exit row seats on delta?
Answer: For a short-haul route from ATL to Savannah (SAV) on Delta's MD-88, exit row seats are sold as Preferred Seating. Prices vary, but for a flight I checked 45 days out, the buy-up to a Preferred exit row seat was $29, while the buy-up to a Comfort+ seat with extra legroom was $44.
