Introduction

Spirit Airlines follows an à-la-carte model, meaning passengers pay only for the services they choose. While this helps keep ticket prices low, it also means being informed about baggage rules is extremely important. The spirit airlines baggage policy outlines what type of bags are allowed, which items require additional fees, and how travelers can save money by planning ahead.

In this 2025 guide, we explain everything you need to know so you can fly stress-free and avoid surprises at the airport.

1. What Bags Are Free on Spirit Airlines?

Spirit Airlines allows one free personal item per passenger. This is included with every ticket and must fit under the seat in front of you.

Personal Item Size Limit:

18 x 14 x 8 inches (45 x 35 x 20 cm)

Examples of acceptable personal items include:

• Small backpacks
  
  

• Laptop bags
  
  

• Handbags
  
  

• Slim duffel bags
  
  

Anything larger than these dimensions is considered a carry-on or checked bag, which will incur additional fees under the spirit airlines baggage policy.

2. Carry-On Bag Rules and Fees

A standard carry-on bag is NOT free on Spirit Airlines. Passengers who want to bring a carry-on must purchase it separately.

Carry-On Bag Size Limit:

22 x 18 x 10 inches (56 x 46 x 25 cm)

Carry-on prices vary based on:

• Route
  
  

• Booking date
  
  

• Membership status
  
  

• Time of purchase (cheapest online, most expensive at the gate)
  
  

Having a carry-on also includes early boarding benefits, making it easier to secure overhead bin space.

3. Checked Bag Requirements and Restrictions

Checked baggage must meet specific size and weight requirements to avoid extra fees. Standard checked bags must not exceed 62 linear inches and must weigh no more than 40 pounds. Anything above that will incur overweight or oversized charges. Understanding these rules is crucial because the spirit airlines baggage policy is very strict about measurements and weights, and fees increase sharply when limits are exceeded.

4. Overweight and Oversized Baggage Fees

If your checked bag is larger or heavier than permitted, Spirit charges additional fees:

Overweight Fees:

• 41–50 lbs: Additional fee
  
  

• 51–70 lbs: Higher fee
  
  

• 71–100 lbs: Even higher fee
  
  

Oversized Fees:

• Bags 63–80 linear inches: Oversize fee applies
  
  

• Bags over 80 linear inches: Not accepted
  
  

Because these fees can be expensive, packing smart and weighing your luggage at home can prevent costly surprises.

5. Tips to Save Money on Spirit Airlines Baggage

Since baggage fees can influence the total cost of your trip, here are practical tips to save:

A. Buy Bags Early Online

Baggage fees are lowest when purchased during booking or before check-in.

B. Join the Saver$ Club

C. Travel Light Whenever Possible

D. Avoid Gate Purchases

E. Share Bags With Family Members

Group packing can help reduce the number of bags needed.

6. Special Items and Sports Equipment

Spirit allows passengers to check special items such as:

• Golf clubs
  
  

• Strollers
  
  

• Car seats
  
  

• Musical instruments
  
  

• Sporting equipment
  
  

These items may require additional fees or packaging requirements. Always check ahead of time for restrictions to avoid issues at the airport.
