    "articleBody": "Nine of the 11 new international nonstops being credited to Southwest Airlines this week can be found in schedule announcements the carrier published itself, and almost all of them depart on a Saturday. The list, compiled from airline scheduling data and shared widely since Monday, October 19, runs from Nashville, Austin, Las Vegas, Columbus and Pittsburgh to Mexico, Costa Rica, Aruba and the islands of the Caribbean between November 2026 and June 2027. We set each route against two Southwest newsroom releases: the spring break 2027 schedule, opened for booking on July 16, and the Summer 2027 schedule, opened on October 2. Here is how the 11 line up. The 11 routes, and what Southwest has put in writing Nashville to Aruba: Saturday-only flights from March 2027, confirmed in the July release. Nashville to Liberia, Costa Rica: the circulating list gives February 13, 2027, but Southwest’s July release groups it with the Saturday-only flights starting in March. Nashville to Nassau, Bahamas, and to Providenciales, Turks and Caicos: new seasonal summer routes, confirmed in the October release. Austin to San José, Costa Rica: new Saturday service, one of two Austin routes the airline said would start in the second week of March. Austin to Liberia, Nassau and Punta Cana, Dominican Republic: weekend flights through June and July, confirmed in the October release. Columbus, Ohio, to Punta Cana: Saturday-only from March, confirmed in the July release. Las Vegas to Puerto Vallarta, Mexico, and Pittsburgh to Punta Cana: listed to start on November 1, 2026, and June 5, 2027. Neither route appears in the two Southwest releases we read. The dates on the list fit that pattern. March 13, 2027, and June 5, 2027, both fall on a Saturday, which is the day Southwest says most of these flights will run. The summer flights sit inside a schedule that the airline says runs from June 3 to August 2, 2027. Why Nashville and Austin get most of them Eight of the 11 routes leave from one of two cities. Southwest says it will offer up to 220 trips at Nashville in Summer 2027, its biggest summer there, about 20 more departures than in Summer 2026. The airline opened a flight crew base in Nashville in 2024. In Austin it plans up to 143 departures, and says it has offered more choice than any rival at that airport for close to 50 years. Construction has started on Southwest lounges at both airports, two of the four it plans to open. Austin already has Southwest flights to Cancun, Los Cabos and Puerto Vallarta, so the new Costa Rica, Bahamas and Dominican Republic services widen a menu rather than start one. In its October release the airline already lists San José among its existing Austin destinations. One route that is missing from the list The July release names a fifth Nashville flight beyond the border: Saturday-only service to Montego Bay, Jamaica, from March 2027. It does not appear among the 11. Nor does Nashville to St. Thomas, which launches the same month, because the U.S. Virgin Islands are a U.S. territory rather than a foreign country. Competition and timing On most of these pairs Southwest would be the only airline flying nonstop, according to the route list. The two Punta Cana routes from Ohio and Pennsylvania are the exception: Breeze Airways plans its own flights there from January 2027, so travelers in Columbus and Pittsburgh may get a choice before Southwest arrives. The whole network is built around Boeing 737s, a fleet of more than 800 aircraft. For the summer season the airline has scheduled 4,498 trips on peak days, the most it has offered in any summer schedule, and it says a separate, compressed July 4 schedule will be published later. For travelers, the practical point is the calendar. Fares for the March flights from Nashville, Austin and Columbus are already bookable under the spring schedule, and the June routes went on sale with the summer schedule on October 2. The earliest start Southwest itself has put in writing for any of the 11 is the second week of March 2027.
