DALLAS, April 18, 2013 /PRNewswire/ -- Southwest Airlines achieved a milestone on April 14 as the carrier began shipping cargo on AirTran Airways under the Southwest Airlines Cargo brand. The airlines successfully completed connectivity of the two networks earlier this year, opening up more destination options and reaching more potential Customers. In addition to broadening the overall cargo network across the two airlines, Southwest introduced four new cargo destinations to their route map: Charlotte, N.C. (CLT); Rochester, N.Y. (ROC); Richmond, Va. (RIC). Beginning May 1, Southwest Airlines Cargo will serve San Juan, Puerto Rico (SJU). Connectivity of the carriers' networks means hundreds of new flights and 68 new nonstop markets for Cargo Customers to experience the reliable service and hardworking Employees that Southwest Airlines Cargo has to offer. "Connecting the Southwest and AirTran Networks opens up a number of opportunities for our cargo service to grow, offering new flights and significant increased capacity for our Cargo Customers," said Matt Buckley, Southwest Airlines Vice President Cargo & Charters. "It's a testament to the success of the AirTran acquisition, and we're excited to offer expanded service to our existing Customers and introduce our product to new ones!" Now, Southwest Airlines Cargo not only can connect through Southwest-to-AirTran flights, but also through AirTran-only or AirTran-to-AirTran flights. Our Cargo Customers in Atlanta (ATL) will see a significant amount of new service, with 90 additional flights available for Cargo, including 22 new nonstop destinations. Many other markets will receive new service, as well. Customers can track their shipments on Southwest Airlines and AirTran Airways though swacargo.com or by using Southwest's GPS tracking device, Cargo Companion.
