Packing for a flight is easy until you reach the baggage-fee section. With Sun Country Airlines baggage allowance, the key point is simple: one personal item is generally included, while an overhead carry-on and checked bags are paid options for many travelers. The exact price can depend on the route and when you purchase the bag.
Sun Country describes its service as an à-la-carte model, allowing passengers to pay for extras such as bags rather than automatically including every service in the base fare.

Sun Country Airlines Baggage Allowance at a Glance
The easiest way to understand the policy is to separate luggage into three categories.
| Bag type | Typical allowance | Maximum size | Weight | Usually included? |
|---|---|---|---|---|
| Personal item | 1 | 17 × 13 × 9 in | No published personal-item weight limit | Yes |
| Carry-on | 1 | 24 × 16 × 11 in | 35 lb | Usually paid |
| Checked bag | Purchased allowance | 62 linear in | 50 lb | Usually paid |
Sun Country’s own published booking guidance lists the same practical size limits: 17 × 13 × 9 inches for an under-seat item, 24 × 16 × 11 inches for an overhead bag, and 62 linear inches/50 pounds for standard checked baggage.
Quick answer: If you want to avoid a standard baggage charge, your safest option is to travel with one personal item that fits completely under the seat. A larger overhead bag or checked suitcase normally requires a purchased baggage allowance.
Sun Country Personal Item Allowance
A personal item is the free bag designed to fit beneath the seat in front of you.
The maximum published dimensions are:
- 17 inches high
- 13 inches wide
- 9 inches deep
That equals approximately 43 × 33 × 23 cm.
A small backpack, purse, laptop bag or compact tote can work well if it fits within those dimensions.
How to tell whether your backpack qualifies
Measure the bag after packing it, not when it is empty.
- Pack everything you expect to take.
- Measure height, width and depth.
- Include bulging pockets and protruding sections.
- Make sure the packed bag can fit beneath the seat.
- Do not assume that a large backpack qualifies simply because it is called a “personal item.”
The practical test is important because a bag that exceeds the personal-item limit may be treated as a different type of baggage and could result in a charge.
Sun Country’s current customer guidance encourages travelers to pack light with a backpack, tote or small duffel when they want to keep costs down.
What can you pack in the personal item?
Typical examples include:
- Wallet and travel documents
- Phone and tablet
- Laptop
- Headphones
- Medication
- Small toiletries
- Travel snacks permitted by TSA
- Change of clothes
- Small camera
Expert tip: Use packing cubes or compression bags inside a soft-sided backpack. This helps you use the available space without making the bag unnecessarily bulky.
Sun Country Carry-On Baggage Allowance
A standard overhead carry-on is larger than the free personal item and is stored in the overhead compartment.
The maximum size is:
24 × 16 × 11 inches, including wheels and handles.
The published weight limit is 35 pounds (15.9 kg).
Is a carry-on free on Sun Country?
For many current Sun Country fares, no. The free allowance is the personal item, while an overhead carry-on is generally a separately purchased option.
This is one of the biggest points of confusion in older online articles. Some older pages describe a free overhead bag, but current Sun Country material says passengers can purchase carry-ons and checked bags as optional services.
Carry-on size checklist
Before leaving home:
- Check that the bag is no larger than 24 × 16 × 11 inches.
- Include wheels and handles in your measurements.
- Keep the weight at or below 35 pounds.
- Purchase the carry-on before arriving at the gate if you need one.
- Keep valuables and essential documents in your personal item.
A bag that is too large for the overhead allowance may need to be checked or may generate an additional charge.
Sun Country Checked Baggage Allowance
Checked baggage is intended for larger luggage that travels in the aircraft’s cargo hold.
The standard published limit is:
- Maximum weight: 50 pounds
- Maximum dimensions: 62 linear inches
Linear inches means:
Length + width + height = total linear inches
For example, a suitcase measuring 30 × 20 × 12 inches equals:
30 + 20 + 12 = 62 linear inches
That suitcase is at the standard dimensional limit.
Sun Country’s contract of carriage confirms that baggage exceeding 62 linear inches or 50 pounds is subject to excess-baggage charges.
Does Sun Country include a free checked bag?
A standard base fare should not automatically be treated as including a free checked bag. Sun Country’s current model separates baggage from the basic transportation fare, although particular fare products, packages, status benefits or qualifying programs can change the cost.
Always check the baggage allowance attached to your specific reservation rather than relying on an older fare comparison.
How Much Does Sun Country Airlines Baggage Allowance Cost?
There is no single universal baggage price that applies to every itinerary.
Recent 2026 baggage guides report approximately:
| Purchase point | Carry-on | First checked bag | Additional checked bags |
|---|---|---|---|
| During booking | About $25–$40 | About $30–$40 | About $45 |
| After booking | About $50 | About $50 | About $60 |
| At airport/gate | About $55 | About $55 | About $65 |
A $10 gate handling fee may also apply when baggage is purchased at the gate. These figures are useful planning ranges, but the exact amount depends on the itinerary and current pricing.
Why baggage prices vary
The final price can depend on:
- Route
- Travel date
- Type of bag
- Number of bags
- When you purchase the allowance
- Applicable membership or card benefits
- Special baggage requirements
The best practice is to check the airline’s current baggage pricing for your exact reservation before travel.
The U.S. Department of Transportation also advises passengers to review an airline’s baggage-fee information because overweight and oversized baggage can create additional charges.
When Is the Cheapest Time to Buy Sun Country Airlines Baggage?
The strongest money-saving rule is straightforward:
If you know you need a bag, add it before you reach the airport.
Sun Country itself says booking is the best stage to add extras such as checked baggage, and recent 2026 pricing guides consistently show higher prices later in the journey.
Best baggage-buying strategy
- Compare the fare price with and without baggage.
- Decide whether a personal item is enough.
- If not, calculate whether a carry-on or checked bag is more useful.
- Add the required baggage during booking when possible.
- Recheck the reservation before departure.
- Avoid waiting until the gate.
This matters because a bag purchased at the airport can cost considerably more than the same bag added during booking.
Sun Country Overweight and Oversized Baggage
A standard checked bag should remain within 50 pounds and 62 linear inches.
If it exceeds either limit, an excess baggage charge may apply.
Sun Country’s contract states that bags over 62 linear inches and/or 50 pounds are subject to excess-baggage charges. The contract also states that Sun Country generally will not accept baggage weighing more than 100 pounds or exceeding 80 linear inches, except for certain large musical instruments covered by its special-item rules.
How to avoid overweight fees
Before leaving home:
- Weigh your suitcase on a luggage scale.
- Keep the bag below 50 pounds.
- Move heavy items into another permitted bag.
- Remove unnecessary shoes and bulky items.
- Measure the suitcase with wheels and handles.
- Do not rely on the suitcase manufacturer’s advertised dimensions alone.
Practical example: If your checked suitcase weighs 54 pounds, moving four pounds of clothing or toiletries into another permitted bag can be cheaper than paying an excess-weight charge.
Sun Country Airlines Baggage for Military Travelers
Active-duty U.S. military travelers may receive special baggage benefits.
However, eligibility and documentation requirements matter. Recent 2026 policy summaries report free-bag benefits for qualifying active-duty military travelers, while Sun Country’s contract confirms that baggage exemptions and reduced fees can apply to eligible passengers.
If you qualify:
- Carry the required military identification.
- Check the current allowance before traveling.
- Confirm whether the benefit applies to your itinerary.
- Do not assume that a companion automatically receives the same benefit.
Because military baggage rules can differ from standard passenger rules, verify the benefit against the current airline policy before packing.
Strollers, Car Seats and Mobility Devices
Families should not automatically count child equipment as ordinary paid baggage.
Sun Country’s contract lists certain child-restraint systems, outerwear and qualifying mobility devices among articles that may be carried without an additional charge under the applicable rules.
Recent airline guidance also indicates that strollers and car seats can be checked without the standard baggage charge in applicable circumstances.
Before traveling with baby equipment
- Check whether the item qualifies for free handling.
- Ask whether it should be checked at the counter or gate.
- Protect valuable equipment from damage.
- Keep essential baby supplies in your personal item.
- Review current rules if traveling internationally.
Sports Equipment and Musical Instruments
Sports equipment and musical instruments can fall under special baggage rules.
Examples include:
- Golf clubs
- Skis
- Fishing equipment
- Bicycles
- Surf equipment
- Musical instruments
The important point is that “allowed” does not always mean “free.”
Special equipment may be subject to baggage, oversized or overweight charges depending on the item and how it is transported.
Sun Country’s contract specifically contains separate provisions for special items, including musical instruments.
If you are traveling with expensive equipment, check the applicable special-item rule before arriving at the airport.
What Happens If Your Sun Country Bag Is Delayed or Damaged?
If your checked baggage is delayed, damaged or missing, report it promptly.
Sun Country’s contract places specific time requirements on mishandled baggage claims. For domestic travel, the contract says a mishandled baggage notice generally must be received within four hours of arrival, unless good cause exists, and the claim must be completed within 45 days of the event.
What to do at the airport
- Report the problem to the baggage service team.
- Keep your baggage tag.
- Keep your boarding pass and booking details.
- Take photographs of visible damage.
- Record the baggage claim or reference number.
- Follow the airline’s claim instructions.
- Keep receipts for reasonable expenses if the airline asks for supporting documentation.
Do not simply leave the airport without reporting a serious baggage problem.
How to Save Money on Sun Country Airlines Baggage Fees
Sun Country’s à-la-carte model can work well for travelers who pack light. The key is to decide what you actually need.
1. Use only the personal item
For a short trip, a 17 × 13 × 9-inch backpack can eliminate the need for an overhead or checked bag.
2. Add baggage early
Recent pricing comparisons show that baggage bought during booking is generally cheaper than baggage purchased later.
3. Compare carry-on versus checked baggage
Do not automatically assume a carry-on is cheaper.
Calculate:
Ticket + carry-on
versus
Ticket + checked bag
Your choice should depend on trip length, packing needs and current itinerary-specific prices.
4. Stay below 50 pounds
Avoid paying an excess fee by weighing your suitcase at home.
5. Use eligible benefits
Qualifying military travelers, certain rewards members, cardholders or package customers may have baggage benefits. Always verify the current terms.
6. Do not wait until the gate
A gate purchase can be significantly more expensive and may also involve a handling charge.
Common Sun Country Airlines Baggage Mistakes
Avoid these common errors:
- Assuming every carry-on is free.
- Treating a large backpack as a personal item.
- Measuring an empty suitcase instead of a packed bag.
- Forgetting wheels and handles.
- Packing a checked bag above 50 pounds.
- Ignoring the 62-linear-inch limit.
- Waiting until the gate to purchase baggage.
- Relying on an old baggage-policy article.
- Assuming another passenger’s baggage allowance applies to you.
- Forgetting that special equipment can have separate rules.
The biggest lesson is simple: check your reservation and the current airline baggage information before leaving for the airport.
