When it comes to finding the Best Time To Book Southwest Flights, the difference between a great deal and an overpriced ticket can come down to just a few days. At Southwest Airlines, known for its transparent pricing and customer-friendly policies, timing truly matters. If you’re looking to unlock the biggest savings and travel smarter, it’s essential to understand the intricacies of how and when to book with precision.
Understanding Southwest’s Unique Fare Structure
Southwest doesn’t follow the typical airline fare model. Instead, they offer three main fare types: Wanna Get Away, Anytime, and Business Select. Among these, the Wanna Get Away fares are the most affordable, and they’re also the ones that fluctuate the most depending on demand and timing.
What makes things trickier is that Southwest doesn’t show its flights on third-party booking platforms. That means tools like Google Flights, Skyscanner, or Expedia won't help you here. You must book directly from the official Southwest website or their mobile app to catch the best fares.
When Is the Best Time To Book Southwest Flights?
Book Between 6 to 8 Weeks Before Departure
From our in-depth analysis, we’ve found that the Best Time To Book Southwest Flights is generally 6 to 8 weeks prior to departure. During this window, Southwest often releases more affordable Wanna Get Away fares before the flight starts to fill up and prices begin to climb.
For domestic routes, this window is often the golden period where prices are the most competitive. For peak travel seasons like Thanksgiving or Christmas, however, booking even earlier — three months or more in advance — is highly recommended.
Book on Tuesdays at 3:00 PM EST
Tuesdays have historically been the best day to book flights across airlines, and Southwest is no exception. Their weekly fare sales usually drop late Monday night, and by Tuesday afternoon (3 PM EST), competitors have typically matched prices, giving you more options and better deals. It's a perfect storm for finding savings.
Track Price Drops with the Low Fare Calendar
Southwest's Low Fare Calendar is a hidden gem for travelers looking to pinpoint the Best Time To Book A Southwest Flight. This tool shows a full month of pricing, allowing you to visually identify the cheapest travel days. Here’s how to use it effectively:
Choose a flexible date range
Look for the lowest displayed fare
Combine with early weekday travel (Tuesday-Wednesday)
Often, you’ll find that flying mid-week saves 20–30% compared to weekend travel.
Take Advantage of Fare Refund Policies
One of the biggest advantages of flying with Southwest is the airline's no change fees and free cancellations on all fares. If you’ve already booked a flight and notice the fare has dropped, you can simply rebook at the lower price and receive the difference in travel credit.
This makes Southwest ideal for early bookings. You’re never penalized for being proactive. As a bonus, this gives savvy travelers the chance to lock in a fare during a sale and recheck weekly for any reductions — a powerful strategy in mastering the Best Time To Book A Flight Southwest.
Use the 860-374-0002 Helpline for Manual Fare Adjustments
If you're not confident navigating the website or app, Southwest provides a dedicated customer support line at 860-374-0002. This number can be used to request help with fare comparisons, rebookings after price drops, and general booking support. Having a live agent assist you in real time ensures you won’t miss out on any limited-time promotions or technical glitches.
Watch for Fare Sales (Every Tuesday & Seasonal Events)
Southwest is famous for its flash sales. These often take place on:
Tuesdays and Wednesdays
Black Friday and Cyber Monday
“Wanna Get Away Day” sales in June
Post-holiday discounts in January
Being subscribed to the Southwest email newsletter or enabling notifications in their mobile app ensures you’re first to know when these deals go live.
Avoid Booking Too Early or Too Late
Contrary to what many believe, booking too far in advance isn’t always the cheapest option. Southwest typically releases flights in batches, often about 6 to 8 months ahead of time. While it might be tempting to book the moment flights are published, it’s often better to wait a few weeks unless there’s a fare sale.
On the flip side, waiting until the last minute — especially under 2 weeks before departure — will usually cost you 30–50% more, especially for popular routes like Las Vegas, Orlando, or Los Angeles.
Use Points Strategically (Rapid Rewards)
If you’re using Southwest’s Rapid Rewards points, the Best Time To Book A Flight Southwest is whenever point values are lowest — and those mirror cash prices. Keep an eye on off-peak travel days and use your points when the Wanna Get Away fares are the cheapest.
Booking early with points also comes with no risk since Southwest allows you to cancel and redeposit points with no fees. Watch for price drops and rebook if needed, maximizing the value of your loyalty currency.
Compare with Third-Party Fare Tools for Trend Analysis
While Southwest doesn’t appear on major comparison sites, you can use platforms like Fareasky to observe general fare trends for similar routes on competing airlines. This can give you a ballpark idea of how prices might behave, even if you must book directly with Southwest.
For instance, if Fareasky shows a consistent decline in fares on Delta or United for a similar route, there’s a good chance Southwest will also match or beat those fares during its next sale. Monitoring both helps you determine the Best Time To Book Southwest Flights with confidence.
