What is the Southwest Airlines low fare calendar?

Unlike traditional airline search tools, Southwest displays both one-way and round-trip fares across flexible dates, making it easier to spot pricing trends and choose flights that match your schedule and budget.

How do you make a booking with Southwest's low fare calendar? 

Southwest fare calendar reveals your route's lowest point redemptions or dollar fares, so you can choose the cheapest travel date and save more.

Here's how it works:

1. Go to Southwest's desktop website. The calendar function is only accessible on the website, not through the mobile version.

2. Enter your departure and arrival cities and click on the "Low Fare Calendar" link rather than picking fixed dates.

3. Scrolling through the monthly calendar will indicate the cheapest dates to fly.

4. Click on your selected date to display particular flight times and fare categories.

Benefits of Using the Low Fare Calendar

Southwest cheap flight calendar isn’t just about cheaper flights — it’s part of a broader customer-friendly pricing policy that includes:

- Two free checked bags per traveler, a rarity among U.S. airlines.

- No cancellation or change fees provided you cancel a minimum of 10 minutes before departure.

Easy rebooking options: If the price falls after you've made your booking, you can rebook at the lower rate and get a credit or points refund.

- Rapid Rewards freedom, use points or pay cash, and earn points on applicable bookings.

The calendar also lets you book up to six months ahead, perfect for long-planners and those wanting to snag Southwest's legendary sales, such as the Birthday Sale or off-season promotions.

Rebooking to Save Even More

One of Southwest Low Fare Finder least appreciated benefits is the option to rebook flights at a lower fare if fares decrease after you've booked. If you paid with points, you'll get the difference back in points. If you paid cash, the difference is returned as a Travel Fund, redeemable for future flights.

To rebook:

- Log in to your reservation online.

- Choose "Change Flight."

- If a cheaper fare is available on the same route and date, rebook and get the difference, no questions asked.

Rapid Rewards and Companion Pass Benefits

The rewards are even better if you're a Southwest Rapid Rewards program member. You can use points to book flights listed on the Southwest Airlines calendar, and even accrue points on third-party portal bookings such as the Chase Ultimate Rewards travel portal.

In addition, if you've acquired the Southwest Companion Pass, which allows someone to travel with you for almost free (just taxes and fees), you can pair that with Low Fare Calendar redemptions for a deal that can't be beat.

Here's how it works: you book a round-trip for yourself for 10,000 points, and your companion rides along for just $11.20 round-trip in taxes. That's traveling smarter, not harder.

Things to Keep in Mind

- Fares can rise during holidays, school breaks, or significant events.

- Blackout dates and advance purchase requirements can exist, particularly during peak travel periods.

- Popular flights sell out fast because the calendar does not reflect real-time availability.

- Certain fares are non-refundable, although you can still cancel and keep the value as Travel Funds.
