Even though we are still in the dog days of winter, it's time to start planning your trips for next summer and fall. You can now book Southwest flights all the way through early November 2025 … and maybe save a ton of money (or Southwest Rapid Rewards points) by booking far in advance!

While most airlines allow you to book flights up to 11 months or more in advance of your travels, Southwest Airlines does it a bit differently. They release their fares in batches, going as far out as about seven to nine months. As of earlier this week, it was only possible to book Southwest Airlines flights into early August – even as other carriers are already selling flights into fall 2025.

But that changed on Thursday, as Southwest has now released another two month's worth of flights. The Southwest flight schedule now has flights bookable all the way through Nov. 1, 2025. So, if you're trying to plan a trip for this summer or all the way through fall, you can book those Southwest flights now.

Thrifty Tip: Every single Southwest ticket includes two free checked bags, making it a great airline for ski trips or the holidays!

Plus, it's easier than ever to find and book Southwest fares. After decades of going alone and only publishing fares on its own site, Southwest expanded to Google Flights last year. The airline then followed up by listing tickets on KAYAK, too.

Nervous about making travel plans all the way into next fall? Southwest always allows free changes or cancellations. That means you can book a flight as far out as early November now, then change or cancel it (for a travel credit) down the line if need be. Southwest also sells new Wanna Get Away Plus fares that allow you a one-time transfer of those travel credits to another person!

And as far as cancelations and refunds go with Southwest, they have always offered some of the most generous policies in the industry. Long before other carriers ditched change fees, there has never been a fee to cancel or change your Southwest flight.

You can cancel any Southwest flight and be given a voucher for later use. It's one of the many reasons we're big fans of Southwest Airlines.

 

Bottom Line

The Southwest flight schedule is now open through Nov. 1, 2025. If you're trying to make travel plans for next fall, you can book those flights now.
