Best Days and Booking Windows
Southwest flights are usually the cheapest on Tuesdays and Wednesdays. On Monday nights, airlines often announce new fares. This gives travelers the chance to watch prices over the next few days to see if they go down. Booking your flights six to eight weeks in advance is a good way to travel within the US. It lets you get good deals on flights without having to pay more for last-minute purchases. You can also save money by traveling on less popular days, like Tuesday or Saturday, when airports are less busy.
Timing for Savings
You should book your trip six to eight weeks before you plan to leave. Changing your departure or return dates by a day or two can save you even more money if you have a flexible schedule. Last-minute deals are sometimes available two weeks before you leave, but they are not always available and depend on how full the flights are. Keeping an eye on prices for a few days will help you spot trends and get the best deal.
Morning vs. Evening Fares
Airlines often release new prices early in the morning, which gives people who stayed up late the chance to get the best deals. Airlines may offer last-minute discounts as they look at unsold seats later in the day, which could change prices. To find trends that work for your route, check fares at the beginning and end of the day for several days in a row.
Seasonal Travel Trends
Being aware of high-demand travel periods helps you avoid inflated prices and crowded flights. Some common peak travel times include
- Summer (June to August), when family vacations increase demand and fares
- December holidays, when gatherings and celebrations raise prices
- Spring break (March to April), which drives up demand on popular routes
Flying just before or after busy times or on a Wednesday can help you save money and feel less stressed. If you plan around these trends, you can get lower fares and have a more comfortable trip.
Flexible Dates for Bigger Discounts
Southwest offers a Low Fare Calendar that displays fares for an entire month, making it easier to identify cheaper travel days. Practical steps include:
- Open the Low Fare Calendar on Southwest.com and enter your travel route
- Scan the calendar to find the lowest fares or compare adjacent months for deeper discounts
- Set alerts or check the site regularly to catch any promotional windows
Using this tool allows you to plan your travel around the best prices instead of being tied to fixed dates, which can lead to substantial savings over time.

Last-Minute Deals
Sometimes waiting to book will get you a deal, but it’s risky. Sometimes, airlines will lower the price of unsold seats one to two weeks before the flight. Southwest lets you change or cancel your flight within 24 hours of booking it, but only under certain conditions. This gives travelers a little bit of wiggle room. If your travel plans are flexible, checking last-minute fares can sometimes save you a lot of money, but there’s no guarantee that they will be available.
Holiday Travel Strategies
Holiday travel requires early planning to avoid high prices. Key strategies include:
- Book at least six to eight weeks in advance to secure reasonable fares
- Fly on less popular days, such as Christmas Eve or New Year’s Day, to avoid crowds and high costs
- Consider early morning or late evening flights, which are often cheaper and less congested
By implementing these strategies, you can reduce costs while maintaining a more comfortable travel experience during busy holiday periods.
Frequent Flyer Programs and Promotions
With Southwest’s Rapid Rewards program, people can earn points on flights that they can use to pay for future trips. It is important to keep an eye on the program’s current rules for how to earn and use points. Also, keeping an eye on sales and promotions, like the “Wanna Get Away” tickets that are cheaper, can help you find the best deals. Signing up for alerts and notifications can also help you save a lot of money on seasonal and limited-time sales.
Setting Price Alerts
Price alerts are an efficient way to monitor fares without constantly checking manually. Best practices include:
- Set alerts for flexible date ranges to capture low fares across multiple options
- Enable real-time notifications on your phone to act quickly when prices drop
- Create alerts for different routes if you are open to alternative destinations
Using multiple alerts ensures you do not miss a sudden drop in fares and allows you to plan your trip strategically.
Avoiding Surge Pricing
High-demand periods can lead to surge pricing. To avoid this, consider:
- Traveling on off-peak days such as Tuesdays and Wednesdays
- Booking six to eight weeks in advance for most domestic trips
- Avoiding peak days around major holidays by leaving a day earlier or later
- Using alerts to quickly secure lower fares when prices drop
These practices help manage costs and make travel planning more predictable and less stressful.
Practical Example
If you’re going from a big city to a beach in late August, for example, start looking at prices in June. Use the Low Fare Calendar to look at different dates and find a fare on a Tuesday that works for you. Set alerts and check prices two weeks before you leave if you want to be able to change your plans at the last minute. Using Southwest’s flexible cancel or change window gives you even more options. Using this method consistently makes booking a process that can be repeated and done quickly.
Final Thoughts
To get the best deals on Southwest flights, you need to plan ahead, be flexible, and pay attention to the time. You can get lower prices by booking six to eight weeks in advance, using the Low Fare Calendar, and setting price alerts. Flying on days when there aren’t many people flying and changing your travel dates by a few days can save you a lot of money. Travelers can save money, avoid stress, and have a smoother experience by making these strategies a regular part of their routine. This way, booking flights won’t be a constant problem. Changing dates and times by even a little bit can save you a lot of money, making travel easier and cheaper.
