Southwest Airlines will add international service from Austin next summer, with new routes linking the Texas capital to Costa Rica, the Bahamas and Punta Cana in the Dominican Republic.

The announcement, reported by The Dallas Morning News, marks another step in Southwest's effort to build Austin into a meaningful operation after years of gradual expansion at the airport. All three destinations are leisure markets. None of them currently anchors a large Southwest international footprint from Austin, and the move signals the carrier's confidence in demand for cross-border vacation travel out of Central Texas through the peak summer season.

Costa Rica, the Bahamas and Punta Cana are established Caribbean and Central American leisure destinations that US carriers have pushed aggressively since the recovery in international tourism. For Southwest, the routes extend a network strategy that pairs domestic strength in Texas with international beach markets — an approach the airline has applied from other gateway cities, including Houston and Fort Lauderdale, where it already operates Caribbean and Latin American service.

Austin itself has become one of the fastest-growing metro areas in the United States, and airlines have responded by adding capacity well beyond what the market historically supported. Southwest's decision to place international leisure routes there, rather than routing passengers through its established gateways, reflects both that local demand growth and the competitive pressure in Austin, where American, Delta and United have all expanded.

The specific launch dates, frequencies and aircraft assignments for the new routes were not detailed in the initial report. Southwest typically publishes summer schedules in stages, and the carrier's full plans for the Austin international expansion — including whether the routes operate seasonally or year-round — will become clear as the summer 2026 booking horizon opens.

For Austin-Bergstrom International Airport, the addition strengthens its international profile, which has already grown in recent years with transatlantic and Mexican service from multiple carriers. For Southwest, the routes represent a test of whether Austin can sustain long-haul leisure demand at the level the carrier has achieved in its traditional international strongholds.

Passengers should expect schedules, fares and route specifics to be confirmed as Southwest loads the summer season into its reservation system.
