Southwest Airlines is launching twice-daily service between Washington Reagan National Airport (DCA) and Lambert-St. Louis International Airport (STL) on September 30.
To promote the new route, Southwest Airlines is offering an introductory fare of $139 one-way in either direction on the route when purchased at www.southwest.com or swabiz.com through August 6 at 11:59 p.m. PT.
This fare is available for travel on Tuesdays, Wednesdays, and Saturdays between October 2 and November 14, 2012 (with a blackout on October 6).
Southwest Airlines began service to Washington Reagan National Airport on July 8, with daily non-stop, round-trip service to Austin.
The new St. Louis service is made possible by Southwest’s recent purchase of four slots at DCA for services within the airport’s government-mandated 1,250-mile service perimeter for most flights.
Southwest Airlines also has been expanding its presence in St. Louis, a market the carrier has served for more than 25 years. Southwest is the largest carrier at Lambert-St. Louis International Airport, with 94 departures a day currently, and DCA is the airline’s 34th destination from the airport.
Dallas-based Southwest has recently added flights between STL and destinations such as Newark, Nashville, New Orleans, Raleigh-Durham, Milwaukee, and Seattle.
The carrier also will begin service between St. Louis and both New York LaGuardia and San Antonio on August 12.
