For peak Thanksgiving travel, fly nonstop from Dallas to Phoenix for $255 round-trip, including all taxes, on US Airways.
Depart DFW on Wednesday night, November 26, returning from PHX on the following Sunday, November 30.
For those who must leave after work on the Wednesday before Thanksgiving, you could do a lot worse than $255. Of course if you're a bit more flexible with your travel dates, you'll find fares are lower for off-peak flights.
