6 Secrets to Get Cheap Southwest Airlines Flights

Southwest Airlines is already known for budget-friendly travel, but there are ways to cut your costs even more. Many travelers miss out on lower fares simply because they don’t know where to look or when to book. That’s where these secrets come in. If you want the cheapest Southwest tickets in 2025, you need to act smart. WinkTravelDeals shares insider strategies that make a real difference. Whether you fly often or occasionally, saving with Southwest is easy if you follow these six simple secrets.
 
Secrets to Get Cheap Southwest Airlines Flights
 

1. Book Southwest Airlines Flights on WinkTravelDeals or Call +1-866-579-8033 for Exclusive Deals

The first rule? Don’t just rely on the airline's website. Sites like WinkTravelDeals often offer access to promo fares or negotiated discounts you won’t find elsewhere. Some fares don’t even show up in public searches. Booking directly through WinkTravelDeals or speaking to a travel agent at +1-866-579-8033 could unlock offers not listed on Southwest’s page.
 
Additionally, WinkTravelDeals provides alerts on limited-time promos or flash sales. If you're booking a round trip or group travel, agents might offer additional discounts. Make it a habit to check here first.
 

2. Use the Southwest Airlines Low Fare Calendar to Find the Cheapest Dates

One of Southwest’s best tools is the Low Fare Calendar. It displays the lowest available fares by day over a month. This helps travelers pick the cheapest days to fly. The tool is especially useful for flexible flyers.
 
Here’s how to use it:
 
  • Visit the Southwest website.
  • Select "Low Fare Calendar" under the booking tab.
  • Choose your departure and arrival cities.
  • Browse the calendar to see the cheapest days to fly.

 

Flights on Tuesdays and Wednesdays tend to be less expensive. Avoid Fridays and Sundays, which are usually peak travel days. Combine the calendar insights with WinkTravelDeals’ price tracking to catch rock-bottom fares.
 

3. Set Fare Alerts to Track Price Drops on Southwest Airlines Flights

Prices change often. By setting fare alerts, you get notified the moment prices drop. WinkTravelDeals and other tools like Google Flights and Hopper offer free alerts. Southwest Airlines also allows you to check and rebook at lower prices due to its no-change-fee policy.
 
Set alerts by:
 
  • Inputting your destination and dates.
  • Receiving emails or app notifications when fares drop.
  • Rebooking if a better fare appears.
 
Because Southwest doesn’t charge change fees, you can always rebook the same flight at a lower fare if the price changes after you’ve booked.
 

4. Redeem Southwest Rapid Rewards Points and Credit Card Benefits to Save More

The Rapid Rewards program is underrated. It allows you to earn points on each flight, which can be used to book future travel. If you have a Southwest co-branded credit card, you earn even faster. Booking flights with points is often cheaper than paying in cash, especially during fare sales.
 
Some tips:
 
  • Sign up for Rapid Rewards (free).
  • Use a Southwest credit card for everyday purchases.
  • Combine your points with fare deals to book reward seats.
 
You can even earn a Companion Pass, which lets one companion fly free with you (only taxes apply) for an entire year. It’s a top-tier perk that can double your travel for half the cost.
 

5. Book Southwest Airlines Flights 6–8 Weeks in Advance for the Best Fares

Booking too early or too late can hurt your chances of a deal. For Southwest Airlines, the sweet spot is usually between 6 and 8 weeks before departure. By this point, early-bird fares have been released, and last-minute price hikes haven’t kicked in yet.
 
Monitor sales trends:
 
  • Southwest often launches fare sales on Tuesdays.
  • These sales typically last through Thursday.
  • Prices may increase on Friday when demand spikes.
 
So, check for new sales weekly and be ready to lock in your fare when it hits the right price range.
 
Ideal booking timeline for different types of routes:
 
Route Type When to Book
Domestic Short-Haul 4–6 weeks out
Domestic Long-Haul 6–8 weeks out
Holiday Travel 2–3 months ahead
 

6. Travel Light on Southwest Airlines Flights and Skip Unnecessary Upgrades

One of the great things about Southwest? Two free Southwest checked bags. That’s rare these days and a huge savings opportunity. But you can still save more by traveling light and skipping extras.
 
Avoid add-ons like:
 
  • EarlyBird Check-In (unless you really need it)
  • Upgraded boarding or Business Select fares (not always necessary)
  • Also, try to avoid food expenses by packing your own snacks, as Southwest does not sell full meals onboard.
 
Another Tip: Southwest operates on an open seating policy. So, if you check-in exactly 24 hours before your flight, you may still grab a decent seat without paying for upgrades.
 

Common Booking Mistakes to Avoid on Southwest Airlines Flights

  • Waiting for a "better" deal: Southwest fare sales don’t last long. Grab the deal when it’s good.
  • Not checking back: Since you can rebook at no cost if the fare drops, it pays to keep checking.
  • Booking round-trip when two one-ways are cheaper: Check both options.
  • Forgetting to apply points or coupons: Don’t miss out on available rewards.

 

Final Thoughts

Flying cheap with Southwest Airlines is about more than luck. It’s about using the tools and perks they already offer. And pairing that with platforms like WinkTravelDeals. The right timing, smart use of reward points, and staying alert for fare drops make a big difference. Try out these six secrets, and you’ll see how affordable your next trip can be.
