Southwest Airlines New Routes Add 9 Flights Starting February 13, 2027
Southwest Airlines new routes added nine new and returning flights to its network, with several starting on February 13, 2027. The additions include service from Buffalo to Miami International Airport and from Columbus to San Juan. Some of the markets have no nonstop service now.
Southwest said it will begin flying from Rochester to Fort Lauderdale, Indianapolis to West Palm Beach, Manchester to Fort Myers, Portland, Maine, to Fort Myers, Providence to Sarasota, Pittsburgh to West Palm Beach and Nashville International Airport to Liberia, Costa Rica. The Nashville route will run weekly and use a 175-seat Boeing 737 MAX 8.
Buffalo and Columbus routes
The Buffalo-to-Miami route gives Southwest entry into a market American Airlines serves seasonally and plans to resume in November. Columbus to San Juan stands out because the market has had no nonstop service at all. Southwest said the route drew 53,000 indirect passengers last year, making it San Juan's ninth-largest unserved domestic market.
Indianapolis to West Palm Beach is one of two markets in the group that currently have no nonstop flights and no scheduled nonstop flights by other carriers in the future. Southwest also said four of the eight markets are currently only served by Breeze Airways. That leaves the airline targeting travelers who have been connecting through other airports or relying on limited seasonal service.
Nashville and Liberia
The Nashville-to-Liberia route covers 1,529 nautical miles each way and will start on February 13. Southwest has flown to Liberia since 2015, and the market drew 11,000 passengers flying indirectly last year, making it the fifth-largest unserved US-Liberia market. Cirium data shows 1.9 million two-way seats in the market in 2026, up 5% from the prior record.
Southwest is also inaugurating 20 routes in early June, with seven launching on June 4 and 13 more on June 6. The airline's new longest ever nonstop service within the Lower 48 states is among those early-June routes, while the February 13 additions extend service into domestic and leisure markets where nonstop options were thin or absent.
For travelers, the immediate change is simple: the airline is opening bookable service on specific city pairs that currently depend on connections or limited seasonal flying. Passengers in Buffalo, Columbus, Indianapolis and Nashville get the clearest changes, because those routes either fill a gap now or restore a path that had not been available nonstop.
