Southwest Airlines announces nonstop service from Pittsburgh International Airport to St. Louis

Southwest Airlines today announced that it will start nonstop service to St. Louis from Pittsburgh International Airport beginning March 10.

The flight will be once daily each way. Southwest will start fares as low as $69 one way.

“We’re thrilled that Southwest has recognized that the Pittsburgh region is growing and that they continue to add nonstop destinations from Pittsburgh International Airport,” Allegheny County Executive Rich Fitzgerald said. “From hi-tech to energy, our region’s economy has pent-up demand for more flights, and we look forward to working with Southwest for the next 10 years and beyond to help us provide that service.”

Southwest launched service from Pittsburgh International Airport on May 4, 2005 with nonstop service to four cities. With today’s announcement, the airline will serve 15 nonstop destinations from Pittsburgh, including Las Vegas, Orlando, and Dallas with nearly 30 flights a day.

“Ten years and counting in serving Allegheny County, this addition makes Southwest the carrier offering more nonstop destinations than any other airline in Pittsburgh,” said David Harvey, Southwest Airlines’ Senior Director of Network Planning & Performance. “We’re in the business of connecting people to what’s important in their lives and a time-saving link to St. Louis clearly fits an important need among business and leisure customers."

The St. Louis flight will depart Pittsburgh daily at 8:25 a.m.

“We were very excited to celebrate Southwest’s 10th anniversary in Pittsburgh earlier this year, and we are delighted that they continue to recognize the need for additional service here at Pittsburgh International Airport,” Allegheny County Airport Authority CEO Christina Cassotis said. “This is emblematic of strong community partnership and support from all of our stakeholders.”

Pittsburgh International Airport currently serves 51 cities nonstop, up from 37 two years ago. Passenger traffic is up about one percent year-to-date.
