Dallas-based Southwest Airlines says it will begin serving Denver International Airport within a matter of months.
The low-cost carrier is planning to announce specifics on the flight schedule and fares during a news conference in Denver sometime next week.
But officials say service will start in early 2006.
Southwest says it's able to expand because of aircraft that became available through Hurricane Katrina-related schedule changes. The resumption of aircraft production at Boeing is also said to be a factor in the airline's decision.
Southwest previously served Denver from 1983 to 1986, via the former Stapleton International Airport.
The airline now serves 61 airports in 31 states.
