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.

Southwest has round-trip flights from Austin (AUS) to Denver (DEN) for $98, NONSTOP. $49 each-way. Flights July to October. Mondays, Tuesdays, and Wednesdays only. Origin/Destination reversible.

Note: Southwest allows for free carry-on, checked-bag, and no change or cancellation fees.

Spirit and Frontier may sometimes have slightly cheaper fares on these dates, but they aren’t worth it in our opinion due to the additional bag fees, poor availability, and excessive fees. Spirit and Frontier seats are 2-to-3 inches smaller (in pitch) than regular airlines.

Note: You can save an additional $150 if you book your Flight+Hotel together as a package and use the 150DOM coupon code on Southwest Vacations.
