![Southwest Just Announced 9 New Routes: See All Nonstop Flights Now [Map]](https://www.mogazmasr.com/uploads/2026/06/06/southwest-airlines-new-routes-d732f2a6_800w.webp)
Southwest Airlines is adding nine new and returning routes, with several set to begin on Feb. 13, 2027, in a move that opens nonstop service in markets that have gone without it and revives flights the carrier has touched before. The biggest additions include Buffalo to Miami, Columbus to San Juan, Rochester to Fort Lauderdale, Indianapolis to West Palm Beach, Manchester, New Hampshire, to Fort Myers, Portland, Maine, to Fort Myers, Providence to Sarasota, Pittsburgh to West Palm Beach and Nashville to Liberia, Costa Rica.
The timing is what makes the package stand out. Travelers searching Southwest Airlines New Routes now are looking at a slate that reaches into both domestic and international leisure flying, while Southwest also has 20 launches scheduled in early June, split between seven routes on June 4 and 13 more on June 6. The airline disclosed the new flying through Enilria on X, and the dates give customers something concrete to plan around instead of a vague expansion promise.
Several of the routes are set to operate mainly on Saturdays, which makes the pattern look less like a broad network overhaul than a targeted push into weekend demand. Columbus to San Juan had no nonstop service at all before Southwest stepped in, and Indianapolis to West Palm Beach also had no nonstop flights and no scheduled service from other carriers on the books. Columbus drew 53,000 indirect passengers last year, with most of them connecting through Orlando, Atlanta, Baltimore, Charlotte and Fort Lauderdale, while Indianapolis had been left entirely to connecting itineraries.
The new flying also lands in crowded or partially covered markets. Four of the eight markets are currently served only by Breeze Airways, while American Airlines flies Miami to Buffalo seasonally and is set to bring that service back in November. Allegiant Air’s Rochester to Fort Lauderdale flights are due to resume in October. Southwest is not entering a vacuum everywhere, but it is stepping into routes where competitors already have a presence or a return planned, which will test whether these mostly leisure schedules can hold up against airlines already established on the same city pairs.
The company is also leaning back into places it has served before. Southwest flew Pittsburgh to West Palm Beach from 2013 to 2018, briefly operated Rochester to Fort Lauderdale in 2020 and touched Providence to Sarasota very briefly in 2023. It began flying to Liberia, Costa Rica, in 2015, and the new Nashville service will run weekly on a 175-seat Boeing 737 MAX 8 over 1,529 nautical miles, or 2,832 km, each way. Nashville generated 11,000 indirect passengers to Liberia last year, and the route was the fifth-largest unserved U.S.-Liberia market.
That Nashville flight also fits a larger pattern at Southwest’s hub and focus airports. BNA is the carrier’s seventh most-served airport by flights, and Transportation Department data suggest 5.5 million Southwest passengers transferred to another service there last year. Cirium data show 1.9 million two-way seats in the U.S.-Costa Rica market in 2026, up 5% from the prior record. Southwest’s chief executive has said up to 12 long-haul routes are likely in the coming years, and this latest round suggests the airline is still deciding how far that reach can go without giving up the low-fare, short-haul work that built the network.
