Southwest has added two gates in Denver to support the launch of five new destinations starting in March.
The two additional gates increase Southwest's total number of gates at the airport from 10 to 12. On 14 March the carrier is introducing a single daily roundtrip flight from Denver to the following markets: Hartford, Connecticut; Boise, Idaho; Detroit, Michigan; Ontario, California; and Washington, Dulles.
Southwest will compete with Frontier and its subsidiary Lynx in Boise, schedules in Innovata show. Frontier operates Airbus A318/A319 in the market while Lynx flies Bombardier Q400 turboprops. United also utilises CRJs flown by SkyWest from Denver to Boise, and mainline narrowbodies.
In Detroit Southwest will complete with Frontier, who flies Airbus narrrowbodies on the route, United Express carrier GoJet and Northwest, who operates Airbus narrowbodies.
For the nonstops to Ontario and Washington Dulles, Southwest is only competing against United, who operates mainline service in the markets.
Southwest also plans to bolster frequencies in several of its Denver markets in May including Sacramento, New Orleans, Tulsa, Portland, Oakland, Baltimore and Seattle. The airline also plans to add a Saturday nonstop flight from Denver to New York LaGuardia.
