It’s time to book your Southwest flights all the way through next summer!

While most airlines allow you to book flights up to 11 months 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 months. As of earlier this week, it was only possible to book Southwest Airlines flights through early April. And Southwest’s plan to extend its flight schedule kept getting delayed.

That finally changed Thursday, as the airline has now released more of its spring and summer schedule for 2021. The Southwest flight schedule now has flights bookable all the way through Aug. 16, 2021! So if you’re trying to plan a trip for next spring or summer, you can book those Southwest flights now.

Nervous about making travel plans with coronavirus still out of control? Southwest always allows free changes or cancellation. That means you can book a flight as far out as August 2021 now, then change or cancel it (for a voucher) down the line if need be.

Read up on how to get the cheapest flights by using Southwest’s low fare calendar!


Booking with the Southwest Flight Schedule

Southwest is one of the few airlines that doesn’t list flights on Google Flights or any online travel agency. That means you’ll always need to start your flight search for Southwest fares directly on their website at

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 for a given time period.

And as far as cancelations and refunds go with Southwest, they offer some of the most generous policies in the industry. Unlike most airlines, there is no 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 are big fans of Southwest Airlines.


Bottom Line

The Southwest flight schedule is now open through Aug. 16, 2021. If you’re trying to make plans for winter or spring, it’s time to start booking!

Trying to plan even further out? Southwest hasn’t announced when it plans to extend its schedule again, so stay tuned.
