Summer is over and fall is in full swing, but it's time to start planning your trips for next summer. You can now book Southwest flights all the way through early August 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 June – even as other carriers are already selling flights into fall 2025.
But that changed this week, as Southwest has now released another two month's worth of flights. The Southwest flight schedule now has flights bookable all the way through Aug. 4, 2025. So if you're trying to plan a trip for this winter, all the way through spring, or even deep into next summer, 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 earlier this year. The airline recently followed up by listing tickets on KAYAK, too.
Nervous about making travel plans all the way into next summer? Southwest always allows free changes or cancellations. That means you can book a flight as far out as early August 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!

Booking the New Southwest Flight Schedule
If your travel dates are flexible, we recommend using Southwest's low fare calendar as it will show you the dates with the cheapest fares over a month-long span.

Otherwise, Google Flights is more powerful than ever with the addition of Southwest. You can use Google's handy, two-month calendar to hone in on the cheapest Southwest flights possible, like these fares from Minneapolis-St. Paul (MSP) to Denver (DEN).
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 Aug. 4, 2025. If you're trying to make travel plans for next summer, you can book those flights now.
Trying to plan something for later next summer or into the fall? You'll have to wait: Southwest says it will extend its schedule again on Dec. 12, releasing flights as far out as Oct. 1.
Can you tell me when I can book for April 17th to 22 2024 on Southwest
Heads up in your first paragraph:
“You can now book Southwest flights all the way into early January 2023”
Should be 2024
Thanks for the heads up. That has been updated.
Looks like they are now saying June 8th for the next batch of flights through January 2024. I was waiting for today to book our early November flight that just missed the cut off last time around, now more waiting!
Darn, we just caught this as well.
Do you know what time of day the new flights are released?
Typically first thing in the morning on the day of the next release.
there are no lower fares (wanna get away) for my destination (Belize) during that time, will they not have lower fares to this destination or will they release them later?
What time do the flights usually open at? I thought maybe midnight but I was wrong.
They should be open now.
Sorry….should have said, “Southwest did NOT publish Wanna Get Away Fares for several cities…….
Southwest did publish Wanna Get Away Fares for several cities for the Holidays (Cancun or Los Cabos over the Thanksgiving). Will these lower fares be released later or will Soutwest NOT offer this fare during that time period?
When can I book a flight for October 2022?
Southwest is set to extend its schedule again, out through Nov. 5, on March 30
Hello! We booked April break for Cancun but only one flight was offered w long layovers. But only the weekend before our trip there a multiple flights to choose from w shorter layovers. Do you know if sw adds flights or it is what it is at this point? Any insight is appreciated! Tysm!
There’s no real rule or pattern around it, but it’s certainly possible that Southwest could add more flights as your trip draws nearer. It’s also possible that your trip comes just after the end of Southwest’s traditional “winter” season schedule, when it flies more to Mexico and the Caribbean and then starts to reduce flights. Could go either way!
Just keep checking!
Thanks! That makes sense!
When will southwest release may and June schedules? I am trying to book Maui.
Southwest says it will extend its schedule again on Dec. 8 — pushing out to flights bookable all the way through Sept. 5.

That is available already today.
Thank you for your help!!
Could you please tell me when I can book for April 13-27 2022?
Southwest says its schedule will extend on Sept. 16 for flights bookable through April 24, 2022.
