New Southwest sale just dropped! Up to 40% off!

Happy Monday San Diego Flyers!

If you’ve been looking for the perfect excuse to plan a trip for late summer, fall, or early winter, here it is. Southwest has launched a new sale offering up to 40% off flights.

While the starting fares aren’t unusually low, this promotion meaningfully reduces prices compared to what we’ve been seeing for the rest of the year.

One of the biggest perks of a large Southwest sale is how other airlines tend to react. Competing carriers often drop their prices on the same routes to stay competitive, which can spark short-term fare battles. Even if you don’t usually fly Southwest, it’s worth checking your preferred routes—airlines like Alaska, American, Delta, and United frequently match or undercut these deals.

Travel availability depends on the route, but discounted fares are most common on midweek flights and Saturdays. Major holiday travel periods, including Labor Day and Thanksgiving weekends, are excluded.

If you’re planning travel between August and December, it’s definitely worth checking prices to see how much you can save on your specific dates.

To find deals, search directly on Southwest’s website and use the “Low Fare Calendar” to spot the cheapest options. You don’t need to manually enter a promo code—the discount is already built into the fare. You can also compare prices using tools like Google Flights.

If you have Rapid Rewards points, this sale applies to award bookings as well—meaning your points can go up to 40% further than usual.

Keep an eye on your inbox and flight prices this week—there’s a good chance other airlines will respond with additional discounts.

Happy travels,
