Packing for a flight is easier when you know exactly what you can take onboard and what may cost extra. Sun Country Airlines baggage regulations allow travelers to bring a personal item, while larger carry-on and checked bags may involve additional charges depending on the fare and options selected. Sun Country’s base-fare approach lets passengers choose the extras they actually need.

What Baggage Can You Bring on Sun Country?
Sun Country generally separates baggage into three categories: a personal item, a carry-on bag, and checked baggage. Each category has its own size and weight requirements.
Your ticket includes a personal item that must fit underneath the seat in front of you. A larger carry-on can go in the overhead bin, but it may need to be purchased separately. Checked luggage is transported in the aircraft’s cargo compartment and is also subject to applicable fees.
Understanding the difference between these options before packing can help you choose the right luggage and avoid unnecessary airport charges.
What Is the Sun Country Personal Item Size?
The sun country personal item size limit is 17 x 13 x 9 inches, including the dimensions needed for the item to fit underneath the seat. Examples include a purse, backpack, laptop bag, or small duffel bag.
This is particularly useful for short trips. A well-organized backpack can often hold clothing, electronics, travel documents, medications, and other essentials without requiring an additional overhead bag.
Tips for Packing a Personal Item
Choose a soft-sided bag when possible because it can be easier to fit beneath the seat. Keep frequently needed items near the top, including:
Passport or government-issued ID
Boarding information
Phone and charger
Medication
Headphones
Small electronics
Travel documents
Essential toiletries
Sun Country also recommends keeping important items such as medications, laptops, lithium-battery items, and other critical belongings in your carry-on rather than checked luggage.
Does Sun Country Allow a Carry-On Bag?
Yes. Sun Country permits passengers to bring one carry-on bag in addition to their personal item, subject to the applicable baggage option and restrictions.
The published maximum carry-on dimensions are 24 x 16 x 11 inches, including wheels, handles, and other protruding parts. The maximum carry-on weight is 35 pounds. The bag must fit into the airline’s approved sizer.
Because a bag that is too large may have to be treated as checked baggage, measuring your suitcase at home is a smart step before leaving for the airport.
What Are Sun Country Baggage Fees?
Sun Country baggage fees depend on the type of bag, when you purchase the baggage option, and other factors related to your itinerary. Sun Country states that purchasing baggage options during booking can provide lower pricing than waiting until later in the travel process.
For this reason, do not assume that adding luggage at the airport will cost the same as selecting it while booking. If you already know that you will need a carry-on or checked bag, review the available baggage options before completing your reservation.
Fees can also change, so travelers should check the latest baggage pricing associated with their specific trip rather than relying on an old fee amount.
What Is the Sun Country Checked Baggage Allowance?
The standard checked-bag limit is 50 pounds, with maximum dimensions of 62 linear inches—calculated by adding the length, width, and height. Bags exceeding the applicable size or weight limits can incur additional charges.
The sun country baggage allowance therefore depends on the baggage type you purchase and the limits that apply to your reservation.
How Can You Avoid Checked-Bag Problems?
Weigh your suitcase at home before traveling. Sun Country specifically advises passengers to check their bag weight in advance because overweight luggage can result in additional fees at the airport.
It is also useful to measure the suitcase with its wheels and handles included. A bag that looks compliant in a store can exceed the airline's dimensions once all external parts are counted.
What Should You Pack in Checked vs. Carry-On Bags?
A simple rule is to place essential and valuable items in your personal item or carry-on whenever possible.
Keep medications, identification, electronics, important documents, and lithium-battery devices accessible rather than putting them in checked luggage. Sun Country’s own travel guidance recommends keeping critical items with you.
Checked luggage is more suitable for larger clothing items, shoes, and other belongings that you do not need during the journey.
Remember that airline baggage rules do not replace TSA restrictions. Certain liquids, sharp objects, batteries, and other items may have separate security requirements, so check TSA guidance before packing.
How Can You Save Money on Baggage?
The easiest approach is to decide how much luggage you genuinely need before booking. Travelers taking a short trip may be able to manage with a personal item, while longer vacations may justify purchasing additional baggage.
Sun Country recommends adding baggage options during booking because prices may be lower than purchasing them later.
Also, avoid packing a few extra items “just in case” if they push your bag over the weight limit. Redistributing items between permitted bags can sometimes help you stay within the applicable restrictions.
