What is happening with Frontier Airlines at McGhee Tyson?

Denver-based Frontier Airlines will discontinue its only Knoxville route after Aug. 17, according to reporting from the Knoxville News Sentinel. The carrier currently flies a regular, direct link to Denver three times a week.

From Denver, Frontier passengers have used connections to destinations such as San Francisco, Seattle, and Cancun. Frontier has served McGhee Tyson since 2011 and has been one of the airport’s six airlines.

In a statement, Frontier said it has “instituted a planned, seasonal pause in our service at TYS” and is “reviewing and finalizing” future schedule plans across its network. The airline said it plans to share more information publicly in the coming months.

Why does this Frontier Airlines news matter for Knoxville travelers?

The pause removes a low-cost nonstop option on a key western hub route. Exact return timing has not been released, so summer and fall itineraries that relied on Frontier may need rebooking.

McGhee Tyson said service “will return in the future,” describing the change as a “seasonal departure according to Frontier.” Airport spokesperson Becky Huckaby told Knox News that Frontier says it will return to East Tennessee with seasonal flights from Knoxville.

Passengers with travel booked beyond the route’s phase-out date are entitled to a refund to the original method of payment under Frontier’s policy. Travelers should check confirmations and contact the airline if their itinerary falls after Aug. 17.

What other Denver options remain after Frontier leaves?

While Frontier steps away, Allegiant, Southwest Airlines, and United also offer nonstop service to Denver from McGhee Tyson. Those carriers can cover some of the gap for Colorado-bound passengers in the near term.

The exit lands amid a busy year for the airport. Southwest entered McGhee Tyson in March 2026, and the field has continued to add flights as passenger totals grow. TheStreet notes Knoxville’s airport recorded 3.6 million travelers in 2025.

Frontier’s Knoxville pause follows earlier summer cuts of more than 20 underperforming routes and permanent exits from Spokane and Sarasota. The airline has previously said it reviews routes based on market demand, seasonality, airport operating costs, and other factors.
