This expansion marks Frontier’s return to several markets it previously served, including routes from Denver to Boise and Spokane, Washington, which were last operated in 2021. The airline’s renewed focus on these cities aims to provide travelers with more affordable options and increased flexibility.

To celebrate the launch of these new routes, Frontier is offering special introductory fares. The starting rates are priced incredibly low: starting at just $19 from Las Vegas to Tucscon and Tuscon to LA, for example, and just $29 from Denver to Boise. Trips that go a farther distance are starting ultra affordable as well, like the DC flight to Puerto Rico starting with the intro rate of $59. You can see the full list of intro rates on Frontier’s site.

With this strategic expansion, Frontier Airlines continues to strengthen its commitment to providing ultra-low-cost travel options, connecting more passengers to a wider array of destinations across the United States and the Caribbean.
