Planning a trip with Spirit Airlines and wondering how to update your baggage options after you've already booked your flight? You're not alone. One of the great things about flying with Spirit is the flexibility they offer for budget-conscious travelers. But that flexibility can also be confusing when it comes to extras like baggage.
In this guide, we’ll walk you through how to change the airline baggage after booking a flight, what to expect with their Spirit Airlines Baggage Policy, and how to avoid paying more than you should.
Understanding Spirit Airlines and Its Baggage Approach
This airline is a popular ultra-low-cost carrier in the U.S. known for its no-frills travel model. That means your ticket covers just the basics—getting you from point A to B. Anything else, including baggage, is available for a fee.
The Spirit Airlines Baggage Policy is designed to give travelers full control over what they pay for. This à la carte pricing helps keep base fares low, but it’s crucial to understand how and when to make baggage changes to save money.
Why You Might Need to Change Baggage After Booking
There are several reasons why you might want to change your baggage selection after booking:
You forgot to add a carry-on or checked bag
You want to upgrade from a carry-on to checked baggage
You’ve decided to pack lighter or heavier
You want to save by buying baggage ahead of time instead of at the airport
Whatever the reason, Spirit allows you to make those changes—but you’ll want to act fast to avoid rising baggage policy and fees.
How to Change Your Spirit Airlines Baggage After Booking
Step 1: Visit the Spirit Airlines Manage Booking Page
To get started, go to the "My Trips" section on the this Airlines website. You’ll need your last name and the confirmation code from your booking.
Tip: This is the fastest and most reliable way to view and update your booking details.
Step 2: Select Your Flight and View Add-ons
Once you access your reservation, you’ll see a list of optional services, including seat selection, baggage, and extras. Select the “Add Bags” option.
This is where you can:
Add a carry-on bag
Add checked baggage
Upgrade or change existing baggage choices
Step 3: Pay for the Changes
Spirit Airlines uses a dynamic pricing system. That means baggage policy and fees are lower the earlier you pay. Prices are highest at the airport and can double compared to online prices.
Important: Pay for baggage at least 24 hours before departure to lock in the lowest rate.
What Is Included in Spirit’s Baggage Policy?
Personal Item (Always Free)
Each passenger is allowed one personal item for free (like a backpack or purse). This must fit under the seat in front of you and follow Spirit’s size limits.
Carry-On and Checked Bags (Paid Options)
Under the Spirit Airlines Baggage Policy, carry-on and checked bags are not included in the ticket price and must be added separately.
Baggage allowance includes:
Carry-on bags: Must fit in the overhead bin
Checked bags: Must be under 40 lbs to avoid overweight charges
Baggage policy and fees vary by:
Travel date
Route
When you pay (earlier is cheaper)
When Can You Make Baggage Changes?
You can change your baggage options any time up to one hour before departure. However, fees increase the closer you get to the travel date.
The Best Time to Add Baggage
The cheapest time to change or add baggage is during the initial booking. After that, use the Manage Booking tool as early as possible. Prices may still be reasonable up to 24 hours before the flight.
