We did a thread on this a while back. Their flight DFW
was like $79 last-minute, and at one point they had 2 flights a day. It was known as the "Dancer Express" for all the go-go dancers from Dallas who used it to fly to New York to make some money. You'd stand in luggage claim and the girls would have giant tubs with their costumes clunking down the chute. With last-minute nonstops on this route at 400+ each way these days, I miss SunJet.
