For travel over the Thanksgiving holiday, fly nonstop from Dallas to New York for $291 round-trip, including all taxes, on American Airlines.
We found seats leaving DFW on Wednesday afternoon, November 26, and returning from JFK on Saturday, November 29. If you're able to stay through the weekend, you'll find fares even lower at $215 returning midweek. Either way, not bad for a holiday fare!
