Southwest Airlines has extended its flight schedule, and you can now book Southwest flights for travel through March 10, 2027.

Here are the details you’ll need to book those winter flights that you’ve had your eye on but couldn’t book until now.

Southwest Airlines Releases Schedule Through March 2027

Southwest Airlines has released its flight schedule through March 10, 2027, so it’s time to book that winter getaway you’ve been thinking about for the beginning of next year. If you’re unsure where to travel, don’t forget that Southwest flies to many vacation spots, including Hawaii and international destinations like Costa Rica and the Caribbean.

Unlike other airlines, which release schedules about 11 months in advance, Southwest releases its schedule in smaller chunks — usually about 8 to 9 months in advance.

Why is this so important, you might ask? Flights tend to increase in price as you get closer to your desired travel dates, so you can often save money by booking flights as soon as they’re released. Since Southwest doesn’t charge change or cancellation fees, there’s no downside to booking early.

If you book your flight with Rapid Rewards points and the price drops, you can change your flight to the lower-priced option and get a points refund. Southwest offers several fare classes, which were recently updated. For instance, if you booked a Basic or Choice fare with cash, you can get a flight credit for the price difference.

If you book a Choice Preferred or Choice Extra ticket, your fare is fully refundable, whether you paid with points or cash.

Hot Tip:

With all of the changes at the airline, you now have ability to choose an assigned seat, based on fare class, elite status, and whether or not you have a Southwest credit card.

When Will the Southwest Schedule Be Extended?

Southwest Airlines releases its flight schedule in small chunks throughout the year. Flights are currently available to book through March 10, 2027.

On July 16 2026, Southwest plans to extend the schedule through April 5, 2027.

Final Thoughts

Southwest Airlines doesn’t release a flight schedule in the same manner as other airlines. Instead, it opts for small chunks of flights released throughout the year.

If you’ve been eyeing a Southwest flight for travel plans at the beginning of next year, you can now reserve travel through March 10, 2027, thanks to the airline extending its schedule.
