Fly from Denver to Dallas for $90 roundtrip on Southwest. If you're in Texas and want to check out the Rocky Mountains, this fare also works from Dallas to Denver.

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.
