Finding affordable airfare is one of the biggest challenges for travelers—especially when prices fluctuate daily. Southwest Airlines offers a powerful but often underutilized tool called the Low Fare Calendar, designed to help travelers quickly identify the cheapest days to fly. When used strategically, this calendar can save travelers hundreds of dollars per trip without sacrificing flexibility or comfort.
This in-depth guide explains how the Southwest Low Fare Calendar works, how to use it step by step, and how to combine it with expert booking strategies to consistently secure the lowest fares. Drawing on consumer research, airline pricing practices, and real-world traveler experiences, this article delivers actionable insights you can use immediately.
Understanding the Southwest Low Fare Calendar
What Is the Southwest Low Fare Calendar?
The Southwest Low Fare Calendar is an online fare-comparison tool that displays the lowest available fares for each day of a selected month on a given route. Instead of searching day by day, travelers can view an entire month’s worth of prices at once.
Unlike many airline calendar tools, Southwest’s calendar:
- Shows actual bookable prices, not estimates
- Includes taxes and mandatory fees upfront
- Works for both cash fares and Rapid Rewards points
This transparency aligns with U.S. Department of Transportation (DOT) airfare advertising rules, which require airlines to display full prices upfront.
Why Southwest Fares Behave Differently
Southwest Airlines operates under a pricing and business model that differs from most legacy carriers.
Key Differences That Affect Pricing
| Feature | Southwest Airlines | Traditional Airlines |
|---|---|---|
| Change fees | None | Often $75–$200 |
| Baggage fees | Two bags free | Usually extra |
| Dynamic repricing | Frequent | Less flexible |
| Fare classes | Simple (Wanna Get Away, Anytime, Business Select) | Complex multi-tier systems |
Step 1: Visit Southwest’s Official Website
Go directly to Southwest.com and select:
- One-way or round-trip
- Departure and arrival cities
- “Low Fare Calendar” instead of specific dates
- Tip from frequent flyers: Searching one-way fares often reveals cheaper combinations than round-trip searches.
Step 2: Choose Your Travel Month
The calendar displays:
- Color-coded fare ranges
- Lowest available fare for each date
- Rapid Rewards point equivalents (if selected)
Southwest typically allows bookings 6–8 months in advance, depending on its schedule release cycle.
Step 3: Compare Multiple Months
Click forward or backward to compare months. Price patterns often emerge:
- Mid-week flights (Tuesday–Wednesday) are often cheapest
- School holidays and weekends trend higher
- Early fall and late winter frequently offer the lowest fares
According to historical airfare trend analyses referenced by Consumer Reports, flexible date searches can reduce airfare costs by up to 30%.
Step 4: Select Fare Type Strategically
Southwest offers three primary fare categories:
| Fare Type | Best For | Refund Policy |
|---|---|---|
| Wanna Get Away | Budget travelers | Flight credit |
| Anytime | Flexibility | Refundable |
| Business Select | Frequent business travelers | Fully refundable + perks |
Step 5: Track and Rebook When Prices Drop
One of Southwest’s biggest advantages is its no change fee policy. If the price drops:
- Rebook the same flight
- Receive the difference as a travel credit or points refund
This practice is widely recommended by consumer advocacy groups, including Consumer Reports, as a way to hedge against price volatility.
Real-World Example: How the Calendar Saves Money
Route: Chicago (MDW) → Orlando (MCO)
Month searched: September
- Friday departure: $189
- Tuesday departure: $98
- Wednesday return instead of Sunday: saves $71
Total savings: $162 for a family of two
This pattern is common during off-peak seasons when demand fluctuates sharply by day.

Seasonal Trends
| Season | Price Trend |
|---|---|
| January–early March | Lowest |
| Late spring | Moderate |
| Summer | High |
| September–early December | Low (excluding holidays) |
Using Rapid Rewards with the Low Fare Calendar
Why Points Redemptions Are Powerful
Southwest ties points prices directly to cash fares. When fares drop:
- Points required drop too
- You can rebook and get points refunded instantly
Unlike many airline loyalty programs, Southwest does not impose blackout dates, aligning with consumer-friendly loyalty practices.
Advanced Expert Tips for Maximum Savings
Combine These Strategies
- Search midweek mornings
- Check multiple nearby airports
- Book early, then re-price weekly
- Use calendar + fare alerts
- Stack with Southwest sales
Airline pricing analysts note that fares often reset during low-traffic booking windows rather than peak browsing hours.
Common Mistakes to Avoid
- Booking too early without rechecking prices
- Ignoring one-way searches
- Overlooking alternate airports
- Waiting for “perfect” prices instead of refundable options
Based on publicly available information, there is no confirmed data supporting the idea that airfare prices always drop closer to departure.
