Sun Country Bag Policy Rules and Sizes

Sun Country Bag Policy Guide

The anxiety of flying with a low-cost carrier usually comes down to avoiding unexpected fees at the boarding gate. If you are researching the sun country bag policy because you are flying to a major stadium for a game, a weekend festival, or a theme park, you need to know exactly what fits in the metal sizer box. This guide covers confirmed personal item sizes, carry-on fees, medical exceptions, and how to pack your event-day gear efficiently. Because airline enforcement can vary by gate agent, aircraft type, or seasonal volume, we prioritize official rules alongside cautious packing strategies to keep your travel day smooth.

Sun Country Airlines does not require a clear bag for travel, though standard TSA "3-1-1" rules for liquids still apply at security checkpoints. The safest bag choice for a free trip is a soft-sided backpack or tote measuring no more than 17 x 13 x 9 inches, which must fit completely under the seat in front of you. All larger carry-on and checked bags require an additional fee. If your bag exceeds the free personal item dimensions at the gate, you will be required to pay a higher gate-check penalty. If you are unsure about your bag size, the safest recommendation is to pre-pay for a carry-on online before arriving at the airport.

How We Check This Policy

At BagPolicyGuide.com, we prioritize data directly from official airline and government (TSA/FAA) sources. Our team separates confirmed official rules from unclear policy wording to provide the most conservative, safe recommendation for travelers. We recognize that policies can fluctuate based on aircraft type, gate agent discretion, and seasonal travel volume, so we focus on the strictest interpretation to help you avoid unexpected fees.

Official Bag Policy Overview

Sun Country operates on an "a la carte" or unbundled model. Your baseline ticket includes only your seat and one small personal item that fits completely under the seat in front of you.

Confirmed Bag Rules:

• Personal Item: Must fit under the seat. Maximum 17 x 13 x 9 inches.
• Carry-on Bag: Must fit in the overhead bin. Maximum 24 x 16 x 11 inches and must not exceed 35 pounds.
• Checked Bag: Maximum 62 linear inches (length + width + height) and must not exceed 50 pounds.

The airline places metal sizer boxes at the check-in counters and boarding gates. If your bag does not fit smoothly inside the appropriate sizer-including all wheels, straps, and handles-the agent will require you to pay a gate fee to board.

What Makes This Bag Policy Different

Sun Country is particularly strict regarding its dimensional limits, much like the Spirit bag policy or Frontier bag rules. However, Sun Country distinctly enforces a 35-pound weight limit for overhead carry-on bags, which many other airlines do not weigh.

Additionally, many Sun Country passengers are flying specifically to attend events, games, or theme parks. Because you are transitioning directly from the airport to a venue, you have to balance the airline's bag size limit with the stadium or park's security rules. The smartest approach is nesting your event gear inside your compliant flight bag.

Allowed Bags and Size Limits

Personal Items

Your single free bag must be 17 x 13 x 9 inches or smaller. Standard examples include:

• Small daypacks and soft-sided backpacks
• Purses or crossbody bags
• Laptop bags and briefcases
• Small tote bags

Carry-on Bags

Standard carry-on suitcases are permitted if you pay the required fee. They must be 24 x 16 x 11 inches or smaller and weigh under 35 pounds. Similar to Breeze Airways bag limits, all wheels and handles must fit within these dimensions.

Small Clutches and Wallets

If you bring a small clutch, fanny pack, or wallet in addition to a backpack, one item must be packed completely inside the other before you board. Sun Country allows strictly one free item per passenger.

Diaper Bags, Medical Bags, and ADA Exceptions

• Diaper Bag Rules: Families traveling with infants or young children are allowed one diaper bag per child free of charge. This does not count against your personal item limit.
• Medical Bag Exception: FAA-approved assistive devices (CPAP machines, portable oxygen concentrators, breast pumps) fly free and do not count toward your carry-on or personal item allowance. Keep these items in a separate bag and notify the gate agent.
• Strollers: Strollers and car seats can be checked at the ticket counter or gate-checked for free.

Prohibited Bags and Items

Sun Country strictly follows TSA and FAA aviation safety guidelines.

• Oversized Bags: Luggage exceeding 100 pounds or 63+ linear inches is generally not accepted.
• Hazardous Materials: No loose lithium batteries, power banks, or e-cigarettes in checked luggage (these must be in the cabin with you).
• Prohibited Items: No explosives, flammable liquids, bear spray, or self-balancing boards (hoverboards). Firearms must be unloaded, declared, and packed in a locked, hard-sided container in checked baggage only.

How Security Screening Works

1. Ticket Counter Drop: If you purchased a checked bag, you will weigh and drop it at the counter or kiosk. Overweight bags (over 50 lbs) incur steep fees.
2. TSA Checkpoint: All passengers undergo standard TSA screening. If you are bringing liquids, gels, or aerosols, they must be 3.4 ounces or smaller and fit into a single, clear, quart-sized bag.
3. The Gate Sizer Check: Before scanning your boarding pass, gate agents look for oversized bags. If your personal item looks large, you will be asked to place it into the metal sizer.
4. Fee Collection: If the bag does not fit into the personal item sizer, the agent will charge your card for the "Gate Carry-on" fee before allowing you to board.

Packing Strategy for Faster Entry

1. Choose the Safest Bag: A soft-sided backpack is much safer than a rigid miniature suitcase. Soft bags can be squished into the metal sizer if they are slightly overpacked.
2. Pack Event Gear Inside: If you need a clear bag policy compliant tote for a stadium, empty it and lay it flat at the bottom of your personal item.
3. Separate Exception Items: Keep medical devices and breast pumps in their own clearly identified bag so they are not accidentally weighed or counted against your free allowance.
4. Use the 3-1-1 Pouch Wisely: Keep your clear liquids bag at the very top of your backpack so you can instantly pull it out at the TSA checkpoint.
5. Make a Backup Plan: If your soft-sided bag is too bulky for the sizer, you can often remove a thick sweater, put it on, and successfully fit the bag into the box.

Security Check Anxiety Tips

• Measure Including Wheels: The most common mistake travelers make is measuring the body of their suitcase but forgetting the wheels and handle. Measure from the floor to the highest point.
• Pre-Pay if Unsure: The fee for a carry-on at booking is much cheaper than the penalty at the gate. If your bag is right on the line of 17x13x9, pre-paying removes all gate anxiety.
• Consolidate at the Gate: Do not approach the boarding scanner holding a coffee, a neck pillow, a shopping bag, and your backpack. Condense everything into your one personal item before your zone is called.
• Stay Polite: If an agent asks you to size your bag, do not argue. Calmly place it in the box. A polite demeanor goes a long way during busy boarding times.

Category-Specific Packing Tips

• Stadium Bag Policy Preparation: Many sports arenas enforce a strict 12x6x12 clear bag rule. Do not use your clear stadium bag as your main flight personal item; it lacks padding, leaves your valuables visible to the whole airport, and is usually smaller than the 17x13x9 airline limit. Pack it inside a soft backpack.
• Theme Park Bag Policy Strategy: If you are flying into Orlando or Anaheim and heading straight to the parks, use a comfortable backpack. You will be walking miles with this bag, so prioritize thick, padded straps over a stiff tote.
• Concert Bag Policy Needs: If you are attending a music festival right after landing, keep your physical tickets, wristbands, and hotel keys in a secure, zipped interior pocket of your personal item so they do not fall out during TSA screening.

Does Sun Country require clear bags for passengers?

No. The airline allows opaque luggage. However, standard TSA rules mandate that all liquids, aerosols, and gels be placed in a clear quart-sized bag for the security checkpoint.

Is a purse considered a personal item?

Yes. If you bring a purse and a backpack, you must fit the purse completely inside the backpack before boarding, or you will be forced to pay for a carry-on bag.

Are diaper bags free on Sun Country?

Yes. Passengers traveling with an infant or small child are allowed one free diaper bag per child, which does not count toward your personal item limit.

What happens if my bag is too big at the gate?

If your bag does not fit in the metal sizer box, the gate agent will require you to pay a "Gate-Check" fee. This is the most expensive baggage tier available.

Can I bring a camera bag?

A standalone camera bag counts as your one allowed personal item. If you also have a backpack, you must pay for a carry-on or fit the camera bag inside it.

Are CPAP machines allowed on board?

Do I have to weigh my personal item?

Sun Country does not officially list a weight limit for the free under-seat personal item, but your paid overhead carry-on bag must be under 35 pounds.

What is the maximum size for a checked bag?

Checked luggage must not exceed 62 linear inches (length + width + height) and must weigh 50 pounds or less to avoid overweight fees.

Does Sun Country have bag lockers?

No. Airlines do not provide lockers for luggage. If you arrive early for an event, you will need to utilize third-party luggage storage services outside the airport or at your hotel.

Conclusion

The safest choice for avoiding fees on a Sun Country flight is packing a soft-sided backpack that strictly adheres to the 17 x 13 x 9 inch limit. By nesting your smaller venue-specific items-like clear stadium totes or festival clutches-inside this main personal item, you can transition smoothly from the airport to your event. If you know your bag will exceed these limits, pre-paying for a carry-on online is the best way to prevent stressful delays and high penalty fees at the boarding gate.

Bag policies can change by event, venue, season, and security team. Always confirm the latest rules on the official venue, park, team, festival, organizer, or event website before you leave. Information is checked for 2026 where available, but official sources should always be treated as the final authority.
