United Airlines is enhancing its position in the Mile High City with another major expansion.

The Chicago-based carrier announced Thursday that it will add eight new routes from its hub at Denver International Airport (DEN) for the summer 2025 season — adding another boost to the carrier’s fastest-growing hub.

The route is highlighted by a brand new, long-haul flight to Rome. This new 5,547-mile seasonal service will begin on May 1, 2025 and will fly daily until September 24, 2025.

On this route, United will deploy Boeing 787-9 Dreamliners with 48 Polaris business-class pods, 21 Premium Plus recliners, 39 Economy Plus extra-legroom seats and 149 standard economy seats.

In addition to United’s new Rome flight, the airline is adding seven new short-haul destinations, three of which are currently unserved by any other airline from Denver.

The full list of destinations includes:

• Buffalo, New York
• Pensacola, Florida
• North Bend, Oregon
• Peoria, Illinois
• Redding, California
• Regina, Saskatchewan, Canada
• Wilmington, North Carolina

Notably, service to Redding, Regina and Wilmington will become new nonstop routes from Denver. Earlier, flying to these cities required connecting elsewhere across the country.

Several new domestic routes, including Pensacola, North Bend and Wilmington, will operate only during the peak summer season.

Overall, United’s Denver expansion follows several other recent investments in the airport. These include brand new United Clubs, a revamped check-in and departures hall and expanded service across the country and around the world.

Southwest Airlines is United’s biggest rival in Denver, and the carriers have been battling for dominance in the city for years. Some of the tactics used by carriers to attract local flyers include targeted advertising and local promotions.

United, for its part, seems committed to Denver for the long haul. The hub has been its fastest growing in years, and it shows no signs of slowing down.

In fact, there have even been rumors in recent years that the airline might consider moving its headquarters to Denver, where it already operates the world’s largest flight training center.

“United’s continued commitment to providing an exceptional travel experience in Denver is underscored by these new routes and the nearly $1 billion in investments we’ve made to enhance and enhance the customer experience,” said Jonah McGrath, vice president of United’s Denver hub. In a statement. “As Denver’s hometown airline, we’re proud to offer more destinations than any other carrier, giving Colorado residents and travelers passing through Denver unparalleled flexibility and options to explore the places they want to visit most.”
