Southwest Airlines Launches Limited-Time $39 Flight Sale — Book Now for Big Summer Savings

Southwest Airlines has just announced a limited-time sale that promises to make summer travel more affordable than ever. With fares as low as $39, the airline’s Wanna Get Away Sale is perfect for those looking to save on their next vacation. However, these deals won’t last long, so travelers should act quickly to secure their seats.

What You Need to Know About the Sale

The Wanna Get Away Sale is available from May 13th to May 22nd, 2025, offering deeply discounted fares for domestic and select international flights. To take advantage of these low fares, all bookings must be made at least 21 days in advance, and travel must occur between June 3rd and November 19th, 2025. However, there are a few important restrictions to keep in mind:

  • Hawaii and San Juan Flights: Discounted fares to these destinations are only available for travel between August 17th and October 3rd, 2025.
  • Blackout Dates: U.S. travel is restricted on September 1st, 2025, while international travel is blocked out from August 28th to September 2nd, 2025.
  • One-Way Fares: These special rates apply only to one-way flights and are nonrefundable, so travelers should double-check their plans before booking.

Changes to Southwest’s Baggage Policy

It’s worth noting that this sale comes as Southwest prepares to end its long-standing “bags fly free” policy, a cornerstone of its customer-friendly approach. Starting May 28th, 2025, passengers will no longer be able to check two bags for free, potentially adding a significant cost to their travel plans. This policy shift is a substantial change for Southwest, which has long marketed itself as a budget-friendly alternative to other carriers.

In addition to the baggage changes, the airline has announced plans to phase out its open boarding system, a hallmark of the Southwest experience, though this change won’t take effect until 2026. These adjustments signal a shift in the airline’s strategy as it looks to compete more aggressively in a crowded market.

How to Book Your Flight

To take advantage of these low fares, head to Southwest’s website and look under Flight Deals and Offers. As always, it’s a good idea to book as early as possible, as these seats tend to sell out quickly.

While this sale offers significant savings, travelers should weigh the impact of the airline’s new baggage fees and upcoming policy changes before booking. Nevertheless, for those looking to escape the daily grind without breaking the bank, this sale could be a welcome opportunity to explore new destinations this summer.
