A right inbound lane closure will be in effect from approximately 8 p.m. on May 28 to 4 a.m. on May 29. Additionally, crews will replace a damaged overhead electronic message board sign on May 28 and 29 on outbound Peña Blvd. (leaving DEN).

Southwest Airlines Celebrates 15 Years of Denver Service


Southwest first launched flights from Denver International Airport on Jan. 3, 2006

DENVER – January 4, 2021 – Southwest Airlines celebrates 15 years of serving Denver International Airport (DEN) in 2021. The carrier inaugurated service in the Mile High City on Jan. 3, 2006, with 13 daily departures to three destinations – Chicago-Midway (MDW), Las Vegas (LAS) and Phoenix (PHX). Today Denver is the largest operation in the Southwest network, averaging 174 departures a day in 2020 and connecting Denver nonstop to more than 70 destinations in 36 U.S. states and Mexico.

“For 15 years Southwest has been a great partner and we’re so pleased the airline continues to grow in Denver, offering nonstop service to more than 70 destinations,” said DEN CEO Kim Day. “We are grateful for Southwest’s commitment to DEN and look forward to many more successful years, including the opening of 16 new Southwest gates on Concourse C-East in 2022.”

During the past 15 years, Southwest has carried more than 175 million passengers through DEN. Notably, Southwest is the largest carrier of domestic origination and destination (O&D) traffic in Denver. In 2020 alone, Southwest expanded its connectivity to Denver with the addition of seven new routes, including winter season service three times daily between Denver and both Steamboat Springs/Hayden and Montrose that began Dec. 19 and runs through April 5. Southwest has announced four new routes for Denver coming this year, including nonstop service to Colorado Springs beginning March 11.

“Our consistent investment in Colorado is a reflection of sustained support from local Southwest Customers who travel with us for vacations, business trips, visits with friends and family—all important moments in their lives that inspire our work to make these connections for Coloradans,” said Jason Van Eaton, Southwest Airlines Senior Vice President of Governmental Affairs and Real Estate. “We’ll continue to partner with Kim and her excellent team at Denver International Airport in the chapter of recovery ahead, by pairing our flexible policies and value with the airport’s awarded passenger experience, underscoring our Dedication to Denver for decades to come.”

Southwest has made tremendous investment in Denver during this time, including the opening of crew bases for Pilots and Flight Attendants in 2012, and the May 2019 groundbreaking of a 130,000-square foot maintenance hangar scheduled to open in first quarter 2022. Southwest signed a lease in February 2020 for 16 additional gates at DEN which, when completed in 2022, will provide the carrier usage of 40 gates total at DEN through 2035.

Today Southwest directly employs more than 4300 people in Denver. Locally based Southwest Employees have logged more than 46,000 hours in volunteer Community service that reaches far beyond the airport. Southwest has supported nearly 600 Denver area organizations with more than $3.2 million in total giving.
