Searching Southwest, I found seats departing Denver DEN on Saturday, October 20, returning from Dallas DFW on Tuesday, October 23.
Other dates are available for travel from late August through mid-December, excluding Thanksgiving travel.
You'll find similar fares between Denver and Dallas-Fort Worth (DFW) on other airlines like American, United, Spirit, and Frontier, but all of these airlines charge extra for checked bags and most even charge extra for carry-on bags on the lowest fares. Southwest generously includes two free checked bags and has no change fees.
See our fare details for booking info. Have a look at our Denver (DEN) listings for a complete look at today's finds. And for more deals to Texas, check out all of our fares to Dallas-Lovefield (DAL) and Dallas-Fort Worth (DFW).
