![Southwest's Massive Expansion: 25 New Nonstop Routes Unveiled [Full List]](https://www.mogazmasr.com/uploads/2026/07/22/southwest-new-nonstop-routes-826f176c_800w.webp)
Southwest Airlines disclosed 25 new and returning routes in a schedule update that adds fresh nonstop options across its network and brings back some flights travelers had not yet seen on the board. The biggest immediate shift is that some of the routes are already on sale while others were only just disclosed, and the mix includes several limited seasonal services that will matter most to people planning ahead for Spring Break and beyond.
That is why the Southwest New Nonstop Routes search is spiking now: the airline is not talking about one or two isolated additions, but a wider network move that reaches from Baltimore/Washington International Thurgood Marshall Airport to Philadelphia International Airport to new or returning links from Nashville International Airport, Austin, Milwaukee, Columbus and other cities. One of the clearest signs of demand is the Baltimore/Washington International Thurgood Marshall Airport to Philadelphia International Airport flight, which was made available last week and will run twice daily.
Schedule analysis using Cirium Diio data shows that 12 of the 22 domestic markets in the update have not previously had nonstop Southwest service, and three of those 12 had never had nonstop flights by any airline. All three additions from Nashville International Airport fall into that group, which makes that city one of the more important pieces of the update rather than just another stop on a long list.
The new and returning map is broad. Southwest will fly from Boise to Los Angeles International Airport daily, from Dallas Love to Detroit Metropolitan Wayne County Airport six times weekly, from Detroit Metropolitan Wayne County Airport to Austin six times weekly, and from Harry Reid International Airport to Boston six times weekly and to Miami daily. It will also run Nashville International Airport to Des Moines daily and to Wichita daily, New York LaGuardia to Orlando three times daily, Orlando to Pensacola daily, Richmond to Tampa daily, Birmingham to Fort Lauderdale-Hollywood International Airport on Saturday, Nashville International Airport to St Thomas on Saturday, Indianapolis to Destin-Fort Walton Beach on Saturday, Harry Reid International Airport to Knoxville on Saturday and Sunday, Louisville to Miami on Saturday, Milwaukee to Panama City on Saturday, Minneapolis to Fort Myers on Saturday, Oklahoma City to Tampa on Saturday, Omaha to Fort Myers on Saturday, and San Diego to Kona and to Lihue on Saturday and Sunday.
But the schedule update also shows the limits of the expansion. Several of the airport pairs will exist only for Spring Break or on short seasonal schedules, which means the new map is not a simple, permanent broadening of the network. Southwest added multiple routes even as it removed what was to be its longest-ever international operation, a reminder that the carrier is still balancing growth in some markets against cuts in others.
The most consequential new international pieces begin on March 13. Southwest will start Austin to San José on Saturdays using the same 737 MAX 8 to operate both legs of the route, will begin Nashville International Airport to Aruba on Saturdays only, and will open John Glenn Columbus International Airport to Punta Cana on Saturdays only. Austin was the United States' fourth-largest unserved market to the capital of Costa Rica, which helps explain why that route stands out even in a crowded update. For travelers, the next phase is not whether Southwest is adding flights. It is which of these new dots on the map survive past the seasonal rush and become part of the airline’s regular network.
