I found seats departing Chicago MDW on Wednesday, March 13, returning from Denver DEN on Tuesday, March 19.
Other dates are available for travel on scattered dates through mid-May. This is a great opportunity for a ski trip in the Rocky Mountains.
See our fare details for booking info.
You'll find lower fares from Chicago's O'Hare Airport (ORD) on Spirit or Frontier, and similar fares on United or American. However, those flights will have Basic Economy restrictions. Southwest's no change fee policy and two free checked bags make it the best choice for this route. Plus, you'll be able to fly out of the smaller Midway Airport (MDW) in Chicago.
