Southwest Low Fare Calendar (2026 Guide) to Book Cheaper Flights

Southwest Low Fare Calendar (also called low-fare finder) is a flexible-date search tool. It shows the lowest airfare for each day of a selected month. The calendar helps you quickly compare dates, identify lower-priced travel windows, and book flights strategically instead of guessing. Booking early and checking multiple months increases your chances of securing better fares.

What Is the Southwest Low Fare Calendar (Low Fare Finder)?

The Southwest Airlines low-fare calendar is a monthly fare-view tool that displays the lowest available airfare for each day within a monthly view.

Rather than searching one date at a time, you see the lowest available price for every day in a month. The system then shows the cheapest fare per day for your route.

Many travelers also refer to it as a Southwest budget calendar because it helps plan trips around lower-cost travel windows. It is best for travelers who -

• Have flexible travel dates
• Want the lowest available airfare
• Are comparing multiple months
• Are planning vacations or family trips

Why Does the Southwest Low Fare Finder Save More Than Standard Search?

A standard flight search checks one date at a time. The Southwest low airfare calendar shows an entire month at once, making price differences obvious.

Example:

On a New York (LaGuardia), NY (LGA) to Los Angeles, CA (LAX) route, Monday, March 23, 2026 shows $159 while Friday shows $204 - a difference of 22.06% (approximately) just by shifting departure by 4 days.

That’s not rare. Midweek prices are often lower than weekend fares.
