What is the Southwest Low Fare Calendar 2025?

The Southwest Low Fare Calendar 2025 is a smart booking tool that allows travelers to check the lowest airfares across an entire month. Instead of checking day-by-day prices, you can instantly compare fares for multiple dates and pick the cheapest option.

Here’s why it stands out for budget-conscious travelers:

Displays the cheapest fares by date: You can spot the most affordable days to fly within seconds.
Covers all destinations: Whether it’s Los Angeles, Chicago, or Orlando, the calendar lists available discounts clearly.
One-way or round-trip: You can check prices for either type of journey without switching screens.
Perfect for flexible travel plans: Ideal for those who don’t have fixed dates and want to fly when prices are lowest.

The best part? It’s available year-round, so you can plan in advance and secure low fares months before your trip.

How to Use the Southwest Low Fare Calendar (Step-by-Step)

Booking through the Southwest Low Fare Calendar takes only a few minutes and doesn’t require any tech skills. It’s designed for simplicity and quick decision-making.

Here’s how you can use it effectively:

Visit the official Southwest Airlines website.
Go to the “Book” section and select “Low Fare Calendar.”
Enter your departure and destination cities.
Choose your travel month to view daily lowest fares.
Click on the cheapest date shown and proceed to booking.

For instance, if you’re planning a trip from Houston to Las Vegas, you might find fares as low as $89 one-way in January, much cheaper than the average $150+ fare. This tool ensures you never overpay when flying Southwest.

Best Time to Book Using the Southwest Low Fare Calendar

While the Low Fare Calendar shows the best available fares, timing your booking correctly matters just as much. Prices fluctuate throughout the year based on demand, season, and promotions.

To make the most of it:

Book 6–8 weeks in advance for the best domestic fares.
Flying midweek (Tuesday or Wednesday) is statistically the cheapest day to travel.
Avoid major holidays like Thanksgiving or Christmas, when prices peak.
Check the calendar regularly, as Southwest updates its fares multiple times a month.

For example, booking a flight from Phoenix to Denver six weeks before departure might cost you $99, while booking just a week before could raise the price to $180. That’s nearly $80 saved just through smart timing.

Flights and Destinations with Maximum Discounts

If you’re wondering where you can find the biggest savings, the Southwest Low Fare Calendar 2025 highlights several U.S. routes that regularly feature heavy discounts. These destinations are perfect for quick weekend trips, family getaways, or business travel.

Here are some of the best low-fare routes to watch:

Las Vegas (LAS): Off-season tickets drop to around $79 round-trip, making it ideal for a quick holiday.
Denver (DEN): One of the most budget-friendly destinations with fares often below $100 in spring.
Orlando (MCO): Family-friendly destination offering round-trip deals starting near $120.
Chicago (MDW): Regular weekday offers under $110, great for work or leisure.

These price drops usually appear when demand slows down or when Southwest introduces seasonal promotions. You can always compare fares on Affluence Travels to ensure you’re getting the lowest ticket available before final booking.

Tips to Maximise Savings on Southwest Airlines

Finding cheap fares is great, but combining smart travel habits with the Low Fare Calendar can help you save even more.

Try these easy, practical tips:

Book early in the morning: Fares reset overnight, and early birds often get the cheapest seats.
Join the Rapid Rewards Program: Every flight earns redeemable points for future trips.
Avoid peak hours: Late-night or early-morning flights are usually cheaper than evening ones.
Watch for fare refunds: Southwest allows rebooking at lower prices without penalties.

Let’s say you book a flight from Austin to Los Angeles for $130, but a week later it drops to $99. You can simply rebook at the new rate and get a travel credit for the difference, no extra charge! That’s how you can keep saving with each trip.

Common Mistakes to Avoid When Using the Calendar

Even though the Southwest Low Fare Calendar 2025 is simple to use, some travelers miss out on the best deals due to small errors. Avoiding these mistakes can ensure maximum savings.

Watch out for these common missteps:

Ignoring flexible dates: Sticking to fixed days limits cheaper flight options.
Skipping early checks: Prices can rise fast; check fares a few weeks before travel.
Not refreshing or rechecking fares: Southwest updates prices multiple times daily.
Missing flash sales: Discount windows sometimes last only a few hours.

Being alert can easily save you between $50–$150 per ticket, especially on popular routes like New York to Dallas or San Diego to Chicago. Checking the calendar often is the key to spotting those short-lived deals.
