How Far in Advance Should You Book Southwest Flights for the Best Price?

Ever wondered if you should book your Southwest flight months in advance or wait for a last-minute deal? It’s a common question, and the answer isn’t one-size-fits-all.
Southwest is unique. You won’t see its fares on Google Flights or Expedia, which means you have to go directly to Southwest to book—and understand how their pricing works. Let’s break down the sweet spot for booking, how far in advance you should lock in tickets, and a few hacks to save along the way.
Southwest uses dynamic pricing, meaning fares fluctuate based on demand, route, and how far out you’re booking. Unlike other airlines, they don’t add sneaky change fees, which actually works in your favor—you can rebook if fares drop and keep the credit.
Airfare studies (like CheapAir’s annual report) show the “prime booking window” for domestic flights is typically 3 weeks to 3 months before travel. With Southwest, this pattern usually holds, though it can shift depending on holidays or peak seasons.

For most domestic routes, the cheapest fares pop up 1–2 months before departure. Booking too early often means you’re paying before sales kick in, while waiting until the last minute can leave you paying premium prices.
Example: A traveler booking Denver–Phoenix saved $120 by purchasing six weeks in advance compared to three months early.
If you’re traveling during holidays, spring break, or summer, don’t wait. Prices climb fast once demand spikes. For these busy seasons, it’s smart to book as soon as Southwest releases its schedule—usually 6–8 months in advance.
Southwest occasionally runs flash sales, but betting on them is risky unless your travel dates are flexible. Last-minute bargains are the exception, not the rule.
One of Southwest’s best features? Frequent fare sales. Think $49 or $59 one-way specials that pop up several times a year, often starting on Tuesday mornings and running for 48–72 hours.
Smart travelers use the Low Fare Calendar to see the cheapest days to fly at a glance.
Traveler story: “I grabbed a $59 San Diego–Las Vegas flight during a 48-hour flash sale—way cheaper than I’d seen a month before.”

This tool lets you scan an entire month for the cheapest fares. It’s a Southwest-exclusive hack that saves tons of time.
Since Southwest has no change fees, you can rebook if the fare drops and keep the credit. One frequent flyer rebooked the same trip twice and saved $150.
Because points are tied to fare cost, they stretch further during sales. Booking with points during the sweet spot = even more value.
