It’s a full United takeover at Denver International Airport (DEN).

The Chicago-based carrier has shared plans to significantly increase its presence and passenger experience at its Colorado hub. The expansion comprises 35 new flights, 6 additional routes, 12 more gates dedicated to United flights, and 3 new United Clubs.

“Denver is one of the fastest growing cities in the country and as the Mile High City’s most flown airline, it’s essential that we maintain the most modern infrastructure and fleet to support our local employees and customers and deliver a great experience,” Scott Kirby, CEO of United, said in a press release.

Let’s dive into the details of United’s thorough Denver expansion.

Denver Becomes Even More Important for United

Operating more flights than any other airline from the airport, United is the dominant carrier in Denver, followed by Southwest.

As part of United’s expansion, new early-morning and evening departures to cities such as Dallas Fort Worth (DFW), Las Vegas (LAS), Los Angeles (LAX), Orlando (MCO), Phoenix (PHX), Portland (PDX), San Diego (SAN), and Seattle (SEA) are being added.

This will increase capacity by 50% at peak times and solidify United’s position as the airline with the most flights from Denver.

Additionally, United will add service from Denver to 6 new destinations, including 4 that don’t currently see nonstop service from the Mile High City, including Dayton, Ohio (DAY); Greensboro, North Carolina (GSO); Lexington, Kentucky (LEX); and San Juan, Puerto Rico (SJU).

In addition to the new routes, Denver passengers will soon benefit from several improvements on the ground as part of United’s almost-$1 billion investment in the airport.

By the middle of 2024, there will be a total of 12 new gates split between the A and B concourses which will help decrease congestion and facilitate the addition of the increase in United flights. Elsewhere, passengers will experience a new check-in lobby, as well as the introduction of user-friendly at-gate technology.

As for lounges, United Club fans can expect a new A Concourse Club to open this summer as well as the grand reopening of the existing 2 B Concourse Clubs, which have been undergoing a significant revamp.

For passengers who prefer to spend as little time as possible at the airport, United recently opened a grab-and-go concept called United Club Fly.
