Southwest to Launch Denver Flights from Knoxville

Southwest Airlines is expanding its Knoxville network with the addition of a new seasonal nonstop route to Denver International Airport, set to begin in April 2026. The service will further strengthen the carrier’s presence at McGhee Tyson Airport, where it recently launched operations.

The Denver route will connect Knoxville travelers directly to one of Southwest’s largest hubs, offering convenient access to the Rocky Mountain region and onward connections across the airline’s national network. The addition builds on Southwest’s strategy to expand into new markets while providing travelers with affordable and flexible flight options.

This latest announcement follows the introduction of nonstop flights from Knoxville to Nashville, Baltimore, Dallas, and Orlando. The growing list of destinations underscores Southwest’s commitment to establishing Knoxville as a key market in its expanding route map.

For local travelers, the new route represents a significant improvement in connectivity, offering both leisure and business passengers a direct link to Denver’s thriving metropolitan area and popular outdoor destinations. Airport officials say the service is expected to stimulate further travel demand and contribute to the region’s economic growth.

Southwest has steadily grown its presence in secondary markets, leveraging its network strength to create new opportunities for regional airports. By adding Denver service, the airline is providing Knoxville travelers with access to a major U.S. gateway while reinforcing its reputation as a low-cost carrier focused on expanding choice and convenience.

The seasonal route will align with peak travel demand, positioning Knoxville for stronger national connectivity.
