How to Avoid Extra Charges on Spirit Airlines Baggage?

Planning a trip with Spirit Airlines? You're probably drawn to the low ticket prices — and for good reason. Spirit is known for being one of the most budget-friendly airlines in the U.S. But what many travelers don’t realize is that the real cost can sneak up in the form of baggage fees. The good news? You can absolutely avoid paying more than you need to by understanding the Spirit Airlines Baggage Policy and making a few smart choices before your flight.

Let’s break down how you can save money and avoid extra charges on your next Spirit flight.

Understanding Spirit Airlines and Their Fee Structure

Spirit Airlines operates on an ultra-low-cost model, which means your base fare covers just the seat. Everything else—like bags, snacks, seat selection—comes at an added cost. This keeps ticket prices low, but it also means travelers need to be proactive and informed about the baggage policy and fees to avoid surprises.

Book Baggage Early to Save Money

Book Online While Booking Your Flight

The cheapest way to add bags is during the booking process. Spirit allows you to add carry-on and checked baggage while reserving your flight. This is often the lowest rate you’ll find.

Pro Tip: Always check the latest Spirit Airlines Baggage Policy before booking, as prices can vary based on the route and travel dates.

Add Bags Before You Get to the Airport

If you missed adding bags during booking, you can still go online later through “My Trips” and add them at a slightly higher price than during booking—but still much cheaper than at the airport.

Avoid this mistake: Waiting until check-in or arriving at the airport without prepaying for bags. That’s when you’ll pay the highest baggage policy and fees.

Know the Allowed Baggage Sizes

What’s Included for Free?

Spirit allows one personal item for free—think a small backpack or purse that fits under the seat. But if it’s too big, they’ll charge you at the gate.

According to the Spirit Airlines Baggage Policy, your free item must not exceed:

• 18 x 14 x 8 inches

Anything bigger counts as a carry-on or checked bag, which costs extra.

Size and Weight Limits

• Carry-on bags must not exceed 22 x 18 x 10 inches.

• Checked baggage must not exceed 62 linear inches or 40 pounds.

Go over those limits? You’ll face additional charges. Spirit charges by weight tiers (41-50 lbs, 51-70 lbs, 71-100 lbs), so keeping your bag under 40 lbs is key to sticking to the basic baggage policy.

Pack Smarter to Stay Within the Free Limit

Use a Personal Item Strategically

Choose a bag that’s exactly the max size allowed for a personal item. There are many travel backpacks on the market designed to fit Spirit’s measurements and still hold a weekend’s worth of clothes.

Smart packing tip: Roll your clothes and use packing cubes. This helps you fit more without adding weight.

Wear Your Bulky Items

Wear your heaviest shoes and jacket while flying. This frees up space in your personal item and helps you stay within your baggage allowance.

Use Spirit Saver$ Club or Bundle It Options

Spirit Saver$ Club

If you fly Spirit often, consider joining their Saver$ Club. You’ll get discounted fares and lower baggage fees. This can make a big difference over multiple trips.

Bundle It

During booking, Spirit offers a “Bundle It” option. This includes bags, seat selection, and other extras for one flat price. Compare the cost to what you’d pay individually—it can sometimes offer solid savings, especially for longer trips.

Weigh Your Bags at Home

Avoid Surprises at the Airport

Use a simple luggage scale at home to weigh your bags before leaving. Staying under the 40-pound limit avoids costly overweight baggage fees.

Remember: Even 1-2 extra pounds can cost you $30 or more.

If you’re unsure whether your bag meets Spirit’s baggage policy, measuring and weighing it ahead of time can be the easiest way to avoid those unexpected gate fees.

Don’t Forget to Recheck Baggage Fees Before Your Flight

Spirit’s fees can vary based on when and how you pay. They may also change depending on the destination or season. Always double-check their baggage policy and fees at least a week before your trip.

Traveling With Others? Share a Bag

Split a Checked Bag

If you’re traveling with a friend or partner, you can share one large checked bag instead of each person bringing a smaller one. Just make sure it stays under 40 pounds to avoid extra fees.

This trick works best when both travelers are light packers. It’s a smart way to make the most of your baggage allowance and reduce total costs.

What Happens If You Pay at the Gate?

Expect to Pay the Most

Gate baggage fees are the highest possible charges under the Spirit Airlines Baggage Policy. For example, a carry-on added at the gate can be up to $99.

Spirit is strict. If your bag doesn’t fit in the personal item sizer at the gate, they’ll charge you—and there’s no way around it.

Avoid this scenario: Measure your bag ahead of time and add all baggage online at least 24 hours before your flight.
