Frontier Airlines Expands Its Footprint with Exciting New Ultra-Low-Cost Nonstop Flights from Seattle Paine Field to Denver, Phoenix, and Las Vegas Starting at Just $69

Frontier Airlines, known as America’s Greenest Airline and traded on Nasdaq under the ticker ULCC, has officially launched service at Seattle Paine Field International Airport (PAE). The ultra-low-cost carrier introduced new nonstop flights to three high-demand destinations: Denver International Airport (DEN), Phoenix Sky Harbor International Airport (PHX), and Harry Reid International Airport in Las Vegas (LAS). Each route will operate twice weekly, providing travelers in the Seattle area with additional affordable options outside the busier Seattle-Tacoma International Airport (SEA), where Frontier already serves seven nonstop destinations. This expansion offers greater convenience for both leisure and business travelers seeking budget-friendly flights from a less crowded airport.

To celebrate the launch, Frontier is offering promotional fares starting as low as $69*, reflecting its commitment to ultra-low-cost travel combined with environmental responsibility. As an industry leader in sustainability, Frontier operates one of the youngest and most fuel-efficient fleets in the U.S., helping to reduce carbon emissions. These new routes to Denver, Phoenix, and Las Vegas connect passengers to vibrant urban centers and popular vacation spots, with convenient schedules designed to suit weekend trips and longer stays alike. Frontier’s arrival at Paine Field not only broadens travel choices for the Pacific Northwest but also reinforces the airline’s mission to make flying more affordable and eco-friendly.

“We are thrilled to launch our ultra-low cost service at PAE, unlocking more affordable and convenient travel options for consumers in the greater Seattle area and throughout Western Washington,” said Jennifer de la Cruz, senior director of corporate communications, Frontier Airlines. “We want to thank the team at PAE for their support and collaboration, and can’t wait to begin flying value-seeking travelers to Denver, Las Vegas, Phoenix, and the many exciting destinations we serve beyond.”

“Frontier’s new service at Paine Field reflects a shared commitment to delivering an exceptional customer experience and offering travelers more choice in Metro Seattle,” said Brett Smith, CEO of Propeller Airports. “Our partnership is built on providing a convenient, comfortable, and efficient alternative for travelers. We’re excited for Frontier’s passengers to discover the unique, best-in-class service that sets Paine Field apart and enjoy the benefits of our growing reach.”
