What’s the Best Time to Book Using the Spirit Airlines Low Fare Calendar?

When it comes to booking cheap flights, timing is everything—especially when flying with budget carriers like Spirit Airlines. One of the best tools Spirit offers for finding affordable travel options is its low fare calendar. But savvy travelers still ask: What’s the best time to book using the Spirit Airlines low fare calendar?

In this article, we’ll break down when and how to use the low fare calendar to your advantage, plus share expert tips to help you lock in the lowest possible fares.

What Is the Spirit Airlines Low Fare Calendar?

The Spirit Airlines low fare calendar is a flexible date search feature that shows you the cheapest available fares across a range of days, typically by the month. Instead of searching one date at a time, this tool allows you to compare prices quickly, which is especially helpful if your travel dates are flexible.

It’s the easiest way to identify when Spirit is offering deals, promotions, or underbooked flights at rock-bottom prices.

When Is the Best Time to Book on Spirit?

1. Book on Tuesdays or Wednesdays

Spirit, like most airlines, typically releases deals on Tuesday afternoons or Wednesday mornings. Checking the low fare calendar during these times can often reveal reduced prices or flash sales.

2. 6 to 8 Weeks Before Departure

For domestic travel, booking 6 to 8 weeks in advance gives you the best balance of price and availability. Spirit’s fare calendar usually reflects the cheapest flights around this window, especially for popular routes.

3. Avoid Peak Seasons

Try to book flights during off-peak seasons like:

  • Late January to early March

  • Late April to early June

  • Mid-September to mid-November

During these times, Spirit lowers prices to fill seats, and the low fare calendar becomes your go-to for budget-friendly options.

4. Travel Midweek

Spirit flights tend to be cheapest on Tuesdays, Wednesdays, and Saturdays. When using the low fare calendar, look for these days first—they’re the least traveled and often show the lowest fares.

5. Look for Last-Minute Deals

Although risky, Spirit sometimes offers great last-minute prices to fill unsold seats. Using the calendar to check flights within the next 7 days can yield surprising discounts—especially if you're open to flying at odd hours.

How to Use the Calendar Effectively

  • Visit Spirit’s website and select “Flights.”

  • Choose your departure and destination cities.

  • Click “Flexible Dates” or “Low Fare Calendar” to view a full month of pricing.

  • Sort by lowest fare and select your travel dates.

  • Proceed to booking—but act quickly, as low fares can disappear fast.

Things to Keep in Mind

  • Spirit’s fares are base fares only – they don’t include bags, seat selection, or extras.

  • Add-ons increase quickly, so factor those in before finalizing your booking.

  • Use Spirit’s $9 Fare Club if you’re a frequent flyer; it can unlock even lower calendar fares.
