Alaska Airlines is launching daily service between Seattle and St. Louis on September 27.

To introduce the new route, Alaska Airlines is offering $109 one-way fares (plus taxes and fees) on tickets purchased by July 1 for travel through November 17, 2010, on select flights between Seattle and St. Louis. To obtain the introductory fare, tickets must be purchased 14 days in advance. The introductory price is good for travel only on Tuesdays and Wednesdays.

“We’re pleased to bring our award-winning customer service to the ‘Gateway to the West,'” says Joe Sprague, Alaska’s vice president of marketing. “With new nonstop service to St. Louis, Alaska and our sister carrier, Horizon Air, together will serve 30 of the top 35 most-visited destinations from Seattle.”

Tickets are available for purchase at or by calling 1-800-ALASKAAIR (1-800-252-7522 or TTY/TDD line 1-800-392-0228).

Alaska Airlines' all-Boeing 737 fleet includes 737-900s like this one photographed flying over Seattle, as well as 737-800s, 737-700s and half-freighter, half-passenger 737-400 Combis. The airline uses its 737-400 Combis for flights within Alaska

The schedule for Alaska Airlines’ Seattle-St. Louis service calls for the flight to depart Seattle-Tacoma International Airport (SEA) at 11:10 a.m. and arrive at Lambert-St. Louis International Airport (STL) at 5:10 p.m. The return flight is timed to leave STL at 6:05 p.m. and arrive back at SEA at 8:35 p.m. All times are based on local time zones.

“We welcome Alaska Airlines. The launch of their new service in St. Louis gives our region reliable nonstop service to Seattle and connections to cities along the West Coast,” says Rhonda Hamm-Niebruegge, director of Lambert-St. Louis International Airport. “We think this is a great fit because Seattle is the second-biggest West Coast destination for St. Louis passengers.”

Travelers can earn double Alaska Airlines Mileage Plan miles on the new flights between September 27 and November 17, 2010. To qualify, customers must register at, and flight miles must be credited to the passenger’s Alaska Airlines Mileage Plan account to earn double miles.

The new Alaska Airlines service will be operated by Boeing 737 aircraft. Inflight service will include Alaska Airlines’ digEplayer, a personal entertainment system offering a variety of movies, television shows, music and other features.
