Why This Sale is a Big Deal

Southwest is known for its customer-friendly policies like no change fees and two free checked bags, making this sale an even sweeter deal. With fares starting at just $49 one-way, you can snag affordable flights to destinations across the continental U.S., Hawaii, and select international markets. You can also find discounts when you book using Southwest Rapid Rewards points.

This is also a good opportunity for those who have already booked upcoming flights with Southwest. The airline makes it easy to rebook. So you should always double check pricing for your flights and re-book if you see a price drop.

Important Terms

• You’ll need to book at least 21 days before your departure to lock in the lowest fares.
• Seats, travel days, and markets are limited, so popular routes may sell out quickly.
• These fares are nonrefundable, though Southwest’s no-fee change policy gives you some wiggle room if plans shift.
• The sale applies to nonstop flights where indicated; otherwise, it’s valid on single connecting services.
• If booking with points, note that government fees (starting at $5.60 per one-way flight) aren’t included.
