Spirit's Carry-On and Checked Bag Costs

Spirit Airlines charges for both carry-on bags and checked luggage on most fares. The airline's basic economy ticket includes one personal item (purse, backpack, or laptop bag that fits under the seat) at no charge. Everything beyond that costs money.

A carry-on roller bag costs $35 if you buy it at the airport, or $30 if you purchase it in advance through Spirit's website or mobile app. A first checked bag runs $35 at the airport or $30 in advance. A second checked bag is $45 at the airport or $40 in advance. These prices are per flight, so a round trip doubles the cost unless you buy the bag allowance upfront for the entire booking.

Spirit occasionally runs promotions where checked bags are free for members of their frequent flyer program (called Free Spirit) or during limited promotional windows. These deals appear on Spirit's homepage and are not permanent.

Key Takeaways

  • One personal item is free on all Spirit fares, but a carry-on roller bag costs $30 to $35 per flight depending on when you buy it.
  • Your first checked bag costs $30 to $35 per flight if purchased in advance, or $35 at the airport.
  • Buying bag allowances when you book your ticket is cheaper than buying them at the airport.
  • Free Spirit frequent flyer members sometimes receive free checked bags, though this benefit varies and is not may provide on all bookings.
  • Baggage fees are charged per flight, so a round trip with two checked bags can cost $120 to $180 depending on when and how you purchase.

How to Buy Baggage Before Your Flight

The cheapest way to add bags is during the booking process on Spirit's website or through their mobile app. When you select your fare and enter passenger details, you will see an option to add bags. Selecting them there locks in the $30 carry-on and $30 first checked bag price.

You can also add bags after booking by logging into your reservation on Spirit's website using your confirmation number and email address. The price remains $30 for carry-on and checked bags if you do this before your flight. Once you arrive at the airport, the price jumps to $35 for carry-on and $35 for the first checked bag.

If you forget to purchase a bag allowance and show up at the airport without one, you can still buy it at the ticket counter or baggage drop. However, you will pay the higher airport rate. There is no way to avoid the fee if you need to bring a bag larger than a personal item.

What Counts as a Personal Item

Spirit's free personal item must fit under the seat in front of you. This typically means a purse, small backpack, laptop bag, or small daypack. The airline does not publish exact dimensions, but the item should be small enough that a flight attendant would not ask you to gate-check it.

A standard roller carry-on suitcase does not fit under the seat and therefore requires a carry-on bag fee. If you try to bring a roller bag without paying for a carry-on allowance, Spirit staff will ask you to check it at the gate, and you will be charged the checked bag fee instead.

Baggage Fees for Connections and Round Trips

Baggage fees explore to each flight segment. If you book a round trip, you pay the fee twice — once for your outbound flight and once for your return. If you have a connection, you pay per flight leg. A round trip with one checked bag costs $60 to $70 depending on whether you buy in advance or at the airport.

Bags are checked through to your final destination on a single booking, so you do not need to claim and recheck them during a connection. However, you still pay the baggage fee for each flight segment in your itinerary.

Oversize and Overweight Bag Charges

Spirit charges extra if your checked bag exceeds 40 pounds or measures more than 62 inches when you add length, width, and depth together. An overweight or oversized bag costs $100 per bag at the airport. You cannot purchase this fee in advance — it is assessed only if your bag exceeds the limits when you check in.

Weigh your bag before you leave home. Most grocery stores, shipping centers, and some pharmacies have scales you can use for free or a small fee. Measuring your bag takes a minute with a tape measure. Paying $100 at the airport is far more expensive than rearranging your packing at home.

Free Spirit Frequent Flyer Program Baggage Benefits

Members of Spirit's Free Spirit frequent flyer program receive one free checked bag on most bookings. You must enroll in the program and use your member number when you book your ticket. The benefit applies to the member whose name is on the reservation, not to all passengers on the booking.

Free Spirit membership is free to join, but the free checked bag benefit is not may provide on all fares. Basic economy fares sometimes exclude the benefit, and promotional fares may have restrictions. When you book, check the fare rules to confirm whether your ticket includes the free bag benefit.

Comparing Spirit Baggage Costs to Other Airlines

Spirit's baggage fees are higher than most traditional carriers. Airlines like Southwest, Alaska, and JetBlue include at least one free checked bag on most fares. Delta, United, and American include one free checked bag for most passengers, though basic economy fares sometimes exclude it.

The trade-off is that Spirit's base fares are often significantly lower than competitors. A Spirit ticket might cost $80 while the same route on another airline costs $150, but adding a carry-on and checked bag to the Spirit fare brings the total closer to the competitor's price. Calculate your total cost including baggage before deciding which airline to book.

Frequently Asked Questions

Can I bring a carry-on bag for free on Spirit?

No. One personal item (purse, backpack, or laptop bag) is free, but a roller carry-on bag costs $30 in advance or $35 at the airport. If you try to bring a carry-on without paying, Spirit will gate-check it and charge you the checked bag fee instead.

What happens if I don't pay for a bag and show up at the airport?

You can purchase a carry-on or checked bag allowance at the ticket counter or baggage drop, but you will pay the airport rate ($35 for carry-on, $35 for first checked bag) instead of the advance purchase price ($30). If you refuse to pay and try to bring an oversized bag, Spirit will not let you board.

Do I have to pay baggage fees on both legs of a round trip?

Yes. Baggage fees are charged per flight segment. A round trip with one checked bag costs $60 to $70 total, depending on whether you purchase in advance or at the airport. Your bag is checked through to your final destination, so you do not need to recheck it during a connection.

Is there a way to avoid Spirit's baggage fees?

The only free bag is a personal item. If you can fit everything into a purse or small backpack, you pay nothing. Otherwise, you must pay for a carry-on or checked bag. Free Spirit frequent flyer members receive one free checked bag on most bookings, but you must enroll in the program and use your member number when you book.

What if my bag is overweight or oversized?

Spirit charges $100 per bag if it exceeds 40 pounds or 62 inches in total dimensions. This fee is assessed at check-in and cannot be purchased in advance. Weigh and measure your bag before you arrive at the airport to avoid this charge.
