southwest airlines new routes just announced a massive expansion, adding 5 new cities to its network for summer 2025.

- Southwest Airlines is launching nonstop service to five new destinations, including a major return to an east coast hub they haven't served in over a decade, with fares starting as low as $49 one-way.

- The new routes tap into underserved markets, such as direct flights from Nashville to Portland, Maine, and from Denver to the popular vacation spot of Cozumel, Mexico, bypassing traditional layover hubs.

- A key strategic move sees Southwest adding daily flights from Chicago Midway to Jackson Hole, Wyoming, directly challenging United's monopoly on that high-demand ski route during peak season.

- Travelers will also see expanded service from Las Vegas to both Savannah, Georgia, and Bozeman, Montana, with these routes scheduled to launch on June 5, 2025, capturing both leisure and outdoor adventure traffic.

- To celebrate, Southwest is running a limited-time flash sale where bookings made within the next 48 hours include double Rapid Rewards points, but seats are expected to sell out within hours due to record demand.
