Southwest Airlines is best known for affordable domestic travel within the United States, but its international network has grown into a strong value proposition for travelers seeking simple, low-fare access to popular vacation destinations. In 2025, Southwest Airlines continues to serve a focused yet strategic list of international destinations across Mexico, the Caribbean, and Central America, catering primarily to leisure travelers.
This in-depth guide breaks down every international destination Southwest Airlines serves in 2025, explains what to expect when flying internationally with Southwest, and provides actionable tips on booking, documentation, baggage, and Rapid Rewards points.
Based on publicly available information, there is no confirmed data suggesting Southwest plans to expand beyond these regions in 2025.
Overview of Southwest Airlines’ International Strategy
Southwest operates a point-to-point network rather than a global hub-and-spoke system. This shapes its international footprint in several ways:
- Focus on short- to medium-haul international routes
- Emphasis on high-demand leisure markets
- No long-haul or transcontinental international flights
- Strong alignment with vacation travel patterns from U.S. gateways
Unlike legacy carriers, Southwest does not partner with international airlines for long-haul connections. This keeps fares simple but limits global reach.
