Unlike the other airlines that do a rolling schedule extension (every day that passes opens another day of schedules), Southwest operates on a different schedule extension. For them, they open it up in blocks and their most recent schedule extension just happened to allow for bookings into August 4, 2025.

Why Book Now?
There are actually a few reasons why you want to book now – even if the prices are not as low as you may want them to be yet.
With people taking to the skies more and some schedules still not as robust as they used to be, this almost guarantees much higher fares for the most popular times and routes. It is best to take advantage of the early bird opportunity to lock in the price now.
Another reason is that the dates right around any of the major travel holidays (like summer season!) almost never go on sale. This means that when the schedule is released is often as cheap as it gets. So, better to book now which is also affected by the next reason…
… You can cancel at any time and get a full points refund or get a travel credit for the full amount paid with cash. This means you can always rebook later if the price drops or cancel the trip altogether and it won’t cost you anything to do that. This way, you at least have a ticket if you decide to go.
The New Southwest Schedule Extension
The new Southwest schedule extension is through August 4, 2025. This gives you the summer months to book, a 2 month addition since the last extension from September.
You can book the new schedule as of today!
