Spirit Baggage Sizes, Weight, Fees & Allowance Guide [2021]

Spirit Airlines offers many affordable rates to meet the specific travel needs of their customers. You can get one-way flights as cheap as $19. You can save more by making use of their special deals like the kids fly free deal that is available while flying Frontier.

The total costs for flying can go up substantially if there are any additional fees involved. One of the factors that can add to the additional fees is your extra luggage. Depending on the size of your carry-on bags or checked baggage, you will incur some additional costs. If you are listing your bags while booking the trip, you will need to pay around $30 for every checked bag, while one carry-on bag will cost you $35 for traveling both ways. If your bags are oversized or overweight, you will need to pay additional charges ranging between $30 and $150.

However, you can avoid these fees by being mindful of what you are carrying. Make sure to include only the essentials in your backpack; this will help you cut back on your baggage weight and size. Thus you can enjoy the benefits of a cheaper ticket better.

Spirit Airlines Carry On Guide

While flying on Spirit Airlines, you are allowed to bring a personal item with measurements up to 18 by 14 by 8 inches for free on board. For a full-sized carry-on, you will have to pay $35 or more after you have purchased the permit to carry the bag on board. These costs will be a bit lower for the $9 Fare Club members.

Choosing the Right Bag

Selecting the right bag will help you avoid any excess bag fees while traveling on Spirit Airlines. A tote bag works well for this purpose. You can also go for a regular size backpack, as long as it does not exceed the maximum measurements.

Most of the small traditional backpacks used by middle schoolers for school are ideal for carry-on purposes. They are large enough and stay within the backpack guidelines. Most larger and fancier backpacks might be too large for the job. Spirit Airlines, however, can be a bit accommodating if your backpack exceeds the guideline limits by a small margin.

If the bag you are carrying goes over the restricted measurements by an inch or so, it won’t cause any problems for you. Only when you are exceeding the measurements a lot will you be charged with additional fees. Try to stick to the limit to be safe.

Carrying the Essentials

After deciding on a personal carry-bag approved by Spirit Airlines guidelines, you should start thinking about the essentials you are going to put inside it. Some of the generally considered items are a wallet, a laptop, a change of clothes tightly folded, including many smaller bags for carrying individual items. You can use a bag for your cables and cords, another one for holding your small clothing items like underwear, shorts and so on. Another bag can be included for make-up and toiletries.

This will ensure that these items remain separate from your small personal carry-on items. By keeping them in different bags, you can prevent them from mingling with each other. If you do not use make-up or any special toiletries, you will be able to save some space. You can then use this space for some extra clothes.

If you can manage going through your weekend trip with the shoes on your feet, you would probably be better off without an extra one in your Spirit Airlines Carry-On. However, you might still be able to make space for a pair of flats in your bag. They weigh less and won’t take up much space. You may also carry a coat on board, if you feel you might need it at your destination.

Supplies for Kids

You may have the option to cut back on how many hair products, shoes, or clothes you are traveling with. But the supplies for your young kids are non-negotiable. You can carry an infant diaper bag aboard without any extra charge if you are flying with a baby. You also need to account for snacks, formula, diapers, wipes, and extra clothes for your kids, even if it is for a small flight. Spirit Airlines also includes provisions for a stroller and a car seat without additional charges.

Pay for One Bag for the Family

If you are going for a short trip without children or other family members, it would be feasible to avoid extra bags and carry-on fees while traveling on Spirit Airlines. You can bring a carry-on according to the free limit of Spirit Airlines. However, if your trip also includes kids and family, it would be worth paying for extra baggage or checking a bag for the whole family.

In this way, everyone will get to bring their free personal item as allowed by the airlines. They will also be able to pack any additional items in a large shared bag that can be paid for. This would be a great time to use any travel credit that you might have on your cards.

General Recommendations

You can load up your free personal item to the maximum to avoid extra charges. However, it would help if you remembered that your personal backpack or purse might get really heavy by doing that. Make sure that you won’t be facing any problems with the extra weight. Go for an additional bag check if you feel it would cause inconvenience while traveling to and from the airport. Also, consider the type of bag you will be using. A backpack can provide better support as compared to a tote bag.

Another factor that you have to consider is whether you have any physical limitations. You might have a medical condition that prevents you from carrying heavy loads. You might have children with you who will be challenging to manage if your hands are tied up with the heavyweight. Furthermore, you might not be able to unpack and retrieve any items on the way from your personal item backpack if you have filled it to the brim.

What Can Be A Personal Item?

Spirit Airlines allows their customers to carry one personal item for free and another carry-on item that is chargeable. Personal items should fit entirely within the smaller sizer box.

Child’s Car Seat and Stroller

Spirit Airlines will allow you to check one stroller and one car seat for each child without any extra charge at the ticket counter. If you are traveling with two children, you can check a double stroller. You can also check the items at the gate and retrieve them after getting off the aircraft.

Spirit Airlines will also allow you to bring an FAA-approved child restraint system or a child harness device. For this, you need to purchase a separate seat for your child. If the car seat is too large for a regular seat, the airlines will help you move to an open seat for your convenience.

Some FAA car seats may not fit within specific seats of the Spirit Airlines aircraft. The car seats will not be assigned to any seat that has been equipped with an inflatable seat belt. Furthermore, the car seats will not be secured to an exit seat or at a row after or before the exit seats. The aircraft has a premium section of seats called the Big Front Seats, which are available for additional costs.

The dimensions for the seats will vary from one Spirit Airlines aircraft to another. For example, in the Airbus 319, the Big Front Seats’ dimensions are 22” on the broadest seat width and 22” on the narrowest seat width. Deluxe Leather Seats on the same aircraft is 17” on the broadest seat width and 151/2” on the narrowest seat width.

  1. I’m going to be using Spirit and I have an overnight bag that is 18x14x8. It has a handle and wheels that tuck in the suitcase. I would like to use this as a personal item. It will contain some clothes and my purse all in the convenience to me.
