How to Use the Southwest Airlines Low Fare Calendar to Find Cheap Flights

When it comes to flying affordably within the United States, Southwest Airlines is often the go-to choice for budget-conscious travelers. One of its most valuable tools is the Southwest Airlines Low Fare Calendar—a feature designed to help passengers discover the cheapest flight options available across a range of dates. Whether you're planning a last-minute getaway or booking months in advance, this calendar can help you score the best deals. In this guide, we’ll show you exactly how to use the Southwest Airlines Low Fare Calendar to find cheap flights and make the most of your travel budget.
What is the Southwest Airlines Low Fare Calendar?
The Southwest Airlines Low Fare Calendar is an online tool that shows the lowest available fares for every day of a specific month. Unlike standard flight search tools that require you to input exact dates, this calendar allows you to compare fares across a flexible range of dates—making it ideal for travelers who have some wiggle room in their schedule.
This feature is especially useful because Southwest doesn’t list its fares on third-party booking platforms like Expedia or Google Flights. So, using the airline's own fare calendar is one of the only ways to truly find their lowest prices.
Benefits of Using the Low Fare Calendar
Before we dive into the “how,” let’s look at why you should use the Southwest Airlines Low Fare Calendar:
· Easily spot the cheapest days to fly
· Maximize travel flexibility and value
· No hidden fees or surprise charges
· Get access to Southwest’s frequent fare sales
· No change fees, so you can reschedule if cheaper flights appear later
Step-by-Step Guide: How to Use the Southwest Airlines Low Fare Calendar
1. Visit the Official Southwest Airlines Website
Start by going to the official website: www.southwest.com. Once there, navigate to the flight booking section on the homepage.
2. Select “Low Fare Calendar” Option
Right below the departure and arrival search boxes, you’ll find an option labeled “Low Fare Calendar.” Click on this to begin.
3. Enter Departure and Arrival Cities
Input your departure city and destination. You don’t need to enter exact dates yet; this is the beauty of using the fare calendar—you’re browsing by month, not by day.
4. Choose the Month You Want to Travel
Select the desired month from the dropdown calendar. You can browse months ahead if you're planning in advance. Southwest typically releases flights 6–8 months in advance, giving you plenty of opportunities to find deals.
5. Browse Fare Options by Day
After selecting your travel month, the calendar will display the lowest available fare for each day. These are color-coded or labeled to help you spot the most budget-friendly dates easily.
You can scroll through the outbound and return fare calendars separately, making it easier to mix and match the cheapest dates for a round-trip journey.
6. Choose Your Departure and Return Dates
Click on the dates that offer the best fare combinations. After selecting your outbound and return flights, you’ll see a summary of your flight, including the fare type (Wanna Get Away, Anytime, or Business Select).
7. Complete the Booking
Proceed to enter passenger information, choose optional add-ons (like EarlyBird Check-In), and complete your booking.
Tips to Maximize Savings with the Low Fare Calendar
Here are some additional strategies to make the most of the Southwest Airlines Low Fare Calendar:
1. Be Flexible With Your Travel Dates
Even one day’s difference can save you hundreds of dollars. Flying on Tuesdays, Wednesdays, or Saturdays often yields the lowest fares.
2. Book During Sales
Southwest frequently runs limited-time sales where fares drop dramatically. Check the Low Fare Calendar during these promotions to spot sale prices easily.
3. Use Rapid Rewards Points
If you’re a member of the Rapid Rewards loyalty program, you can use points instead of cash. The fare calendar also shows the cheapest points-required for each day, making it easy to use your miles wisely.
4. Monitor and Rebook if Fares Drop
Southwest doesn’t charge change fees. If you book a flight and the price later drops, you can rebook at the lower price and receive a credit for the difference.
