Spirit Airlines Baggage Policy: Carry-On, Checked Bags & Fees Explained

Spirit Airlines Baggage Policy is important to understand before booking because the airline follows a low-fare, pay-for-extras model. Your ticket includes only a personal item, while carry-on and checked bags require additional fees. Knowing size limits, weight rules, and when to purchase baggage in advance helps travelers avoid high airport charges and enjoy a smoother, stress-free trip.

Personal Item (Free)

Every passenger is allowed one free personal item. This must fit completely under the seat in front of you.

Maximum size: 18 x 14 x 8 inches (45 x 35 x 20 cm)

Common examples:

• Small backpack

• Laptop bag

• Purse

• Camera bag

If it doesn’t fit under the seat, Spirit will charge you at the gate and gate fees are the most expensive.

Tip: Soft bags are easier to fit in the sizer and help you avoid charges.

Carry-On Bag (Paid)

Spirit does NOT include a full carry-on bag with standard tickets. You must purchase it separately.

Maximum carry-on size: 22 x 18 x 10 inches (56 x 46 x 25 cm) including wheels and handles

Typical items:

• Small suitcase

• Duffel bag

• Large backpack

Carry-On Fees (Approximate)

When You Buy	Price Range
During booking	Cheapest
Before check-in	Higher
At airport counter	Expensive
At gate	Most expensive

Buying online early can cut the cost by more than half.

Checked Baggage

You can check multiple bags, but each one costs extra.

Weight limit: 40 lbs (18.1 kg) per bag 

Maximum size: 62 linear inches (length + width + height)

If your bag weighs over 40 lbs, overweight charges apply immediately.

Checked Bag Fees

Fees depend on route and timing, but generally:

• First checked bag: lowest online price

• Additional bags: higher price

• Airport payment: much more expensive

Always prepay online to save money.

Overweight & Oversized Fees

Condition	Extra Charge
41–50 lbs	Overweight fee
51–70 lbs	Higher overweight fee
Over 70 lbs	Not accepted
Over 62 inches	Oversized fee

Spirit strictly enforces these limits even one pound over can trigger a fee.

Special Items

Some items have special rules:

Sports Equipment

• Golf clubs, skis, and surfboards allowed

• Fees vary by size and route

Musical Instruments

• Small instruments can be carry-on if they fit

• Larger ones require a seat purchase or checked handling

Strollers & Car Seats

• Free when traveling with a child

Smart Packing Tips to Avoid Fees

1. Use Only a Personal Item

Many travelers avoid baggage fees entirely by packing light in a compliant backpack.

2. Prepay Bags Online

Booking baggage early is the single biggest cost saver.

3. Weigh Your Bag at Home

Use a luggage scale — airport scales never favor passengers.

4. Wear Bulky Items

Jackets, hoodies, and sneakers reduce bag weight.

5. Join Bundle Options

Spirit’s bundle packages often include baggage cheaper than buying separately

What Happens at the Gate?

This is where travelers pay the most.

If your bag:

• Doesn’t fit the sizer

• Is overweight

• Was not prepaid

You’ll be charged the highest fee immediately before boarding.

Gate agents do not waive fees even if the flight is empty.

Final Thoughts

Spirit Airlines keeps fares low by charging only for what you use. If you understand the baggage rules, you can fly very cheaply. The key is simple: pack small, measure carefully, and purchase bags early.

Travelers who prepare ahead often pay half the price compared to those who wait until the airport. Knowing these baggage rules helps you avoid surprises and enjoy a smooth, stress-free trip.
