Southwest has round-trip flights from Austin (AUS) to Denver (DEN) for $98, NONSTOP. $49 each-way. Flights August to October. No Weekends. Origin/Destination reversible.

Southwest allows for free carry-on, two free checked-bags, free change/cancellation and free in-flight refreshments.

Frontier also has round-trip flights for $55-$69, NONSTOP. $28-$35 each-way. Flights August to March. A few weekends available. Origin/Destination reversible.

Frontier allows for nothing. They charge a fee to change or cancel the ticket, they charge a fee for seats, a fee for any bag bigger than a small backpack and their seat pitch is 28-inches. No free refreshments. Water isn’t free.

We believe that the Southwest fare will be a better deal if you are planning on packing a real carry-on or checked bag, but Frontier has a few weekends available, and Southwest doesn’t.

Note: You may find additional savings if you book your Flight+Hotel together as a package on Southwest Vacations. Before you commit, always compare the prices of the individual Flights and Hotel with other hotel booking sites like Hotels.com or HotelsCombined.

If you plan on booking a hotel, use our travel coupon codes to save up to 15% to 20% off. Alternatively, you may be able to save the most money by booking your trip as a Flight + Hotel package on Priceline, Travelocity, or Orbitz.

Note: OTAs such as Travelocity and Priceline allow free cancellation without penalty within 24-hours after you purchase. As deals sell-out or expire quickly, this policy will allow you to “lock-in” the cheap fare while you sort out a plan. Just keep in mind that after 24-hours, you will not be able to cancel without the regular penalty.
