(831-298-4213) – Ever wondered if booking a Southwest flight on a Tuesday really gets you the cheapest fare? You’re not alone. Travelers swap myths about “secret booking windows,” but the truth is a mix of timing, strategy, and knowing how Southwest’s pricing model works.
Let’s cut through the noise and figure out when you’ll really find the lowest fares.
How Southwest Airlines Pricing Works
Unlike most airlines, Southwest doesn’t show up on Google Flights, Expedia, or Kayak. If you want to see their fares, you’ve got to search directly on their site or app.
Southwest uses
dynamic pricing, which means fares shift based on demand, time of year, and availability. Industry studies (like CheapAir’s Annual Airfare Study) show that the “prime booking window” for U.S. domestic flights is usually
21–60 days before departure.
Visual idea: A chart showing price dips around 1–2 months out.
When’s the Best Time to Book Southwest Flights for Cheap Fares?
The Sweet Spot: 3–8 Weeks Out
Most travelers find the lowest fares
about 1–2 months before departure. Book too early and prices may still be high; book too late and last-minute demand drives them up.
Example: An Austin–Denver flyer saved $120 by booking 6 weeks out instead of 3 months early.
Tuesdays & Thursdays (Fare Drops)
Southwest often rolls out new fare sales on
Tuesday mornings. By Tuesday afternoon, competitors may match them, creating short windows of cheap fares.
Off-Peak Travel Seasons
You’ll almost always save more traveling in the “shoulder seasons”:
- Cheapest: Mid-January through early March, late August through October.
- Expensive: Summer, spring break, Thanksgiving, and Christmas.
Watch for Southwest Flight Sales & Specials
Southwest is famous for its flash sales—like $49 one-way “Wanna Get Away” deals. These typically pop up on Tuesdays and last 48–72 hours.
Smart move: Sign up for
Southwest’s email alerts or check their
Low Fare Calendar to see the cheapest days to fly.
Traveler story: “I snagged a $49 San Diego–Las Vegas ticket during a 72-hour flash sale.”
Hacks to Always Get the Best Southwest Fare
Use the Low Fare Calendar
This built-in tool shows you a month’s worth of fares in one view. It’s the easiest way to spot cheap days.
Rebook When Prices Drop
Southwest’s biggest perk:
no change fees. If your fare drops after booking, just rebook at the lower price and get the credit back.
One San Diego flyer rebooked the same trip three times and saved $180.
Use Rapid Rewards Points
Points are tied to fare prices—so redeeming during a sale stretches your points further.

Is It Better to Book Early or Wait?
It depends:
- Book early if you’re traveling on peak dates (holidays, spring break, summer weekends). Prices rarely fall much.
- Wait and watch if your dates are flexible. The sweet spot is usually 21–60 days before your trip.
Balanced advice: Book early for peace of mind, but set reminders to check back—Southwest makes rebooking painless.
Final Thoughts — Timing Your Southwest Flight Bookings
There’s no magic button, but here’s the formula:
- Aim to book 1–2 months out.
- Check Tuesday sales.
- Use the Low Fare Calendar.
- Rebook if fares drop—because Southwest lets you.
That combination gives you the best shot at rock-bottom fares.
