If you’re planning to travel with just a carry-on, you’ll need to be up to speed with your airline’s carry-on policy. Each airline’s rules are different, so don’t just assume what works for one, will work for all airlines. This is especially true if you’re flying a low-cost airline, like Sun Country.
Low-cost airlines may have lower base fares, but if you aren’t careful, you’ll end up paying more because of all the “a la carte” fees they have. These include fees for both checked and carry-on luggage (as well as seat assignments, beverages, printing your boarding pass, etc..). This is especially true when flying Spirit or Frontier Airlines.
If you are going to be flying Sun Country, here are the carry-on rules you need to be aware of regarding size, weight, fees, liquids, etc.
Sun Country Carry-On Size and Weight Limits
Sun Country allows one personal item onboard at no charge, but they charge for both carry-on and checked bags. The personal item must fit under the seat in front of you, and the carry-on bag must be stowed in the overhead bin or it will have to be checked.

Sun Country Airlines Carry-On Size Dimensions
Sun Country’s size requirements for a carry-on are 24″ x 16″ x 11″.
Carry-on bag fees vary based on when you purchase and are non-refundable. The following are the fees you will pay for your carry-on, each way, depending on your destination.
- During Booking: up to $30
- Before & During Online Check-In: $35
- At the Airport: $40
Sun Country Personal Item Size & Fees
Personal items include a purse, briefcase, laptop, backpack, or a similar-sized item. Dimensions must not exceed 17 x 13 x 9 inches.
Carry-On Weight Limits
Sun Country requires your carry-on bag to be less than 35 pounds.
Carry-On Liquids: Sun Country Liquid Policy
The rules for carry-on liquids are set by the TSA (Transportation Security Administration), not by the airline. Sun Country doesn’t have its own specific Liquids Policy, they just enforce the rules and policies of the TSA.
It’s also important to note that the rules for bringing a “liquid” in your carry-on bag are different from the rules that govern what you can bring in your checked luggage. Liquids in a carry-on bag must be 3.4 ounces or smaller and fit in a 1 quart-sized container. Anything larger must be placed in your checked luggage.

The TSA 3-1-1 Rule
You may carry liquids, gels, and aerosols in travel-size containers that are 3.4 ounces or 100 milliliters. Each passenger is limited to one quart-size bag of liquids, gels, and aerosols. Common travel items that must comply with the 3-1-1 liquids rule include toothpaste, shampoo, conditioner, perfume, mouthwash, deodorant, and lotion.
Any liquid that does not meet the TSA 3-1-1 rule will either have to be checked with your luggage or will be thrown away at the security checkpoint.
Here is a little video to help illustrate:
Exceptions to this rule are certain medications and baby food/child nourishment.
Carry-On Food
The TSA also sets the rules for what type of food you can bring on the plane. There are two different scenarios pertaining to food:
- The food you bring with you from home, and
- The food you buy at the airport after you have gone through security.
When bringing food with you from home, an important thing to note is the classification of liquid vs. solid foods.
The general rule is “If you can spill it, spread it, spray it, pump it, or pour it, then it’s considered a liquid or gel,”. This means your food may be considered a liquid and will fall under the TSA 3-1-1 liquids rule, which mandates that any liquid, gel, cream, aerosol, or paste in a carry-on must be 3.4 ounces or less, and fit in one quart-size resealable bag (only one such bag is allowed per passenger).
Here’s a link to the TSA website advising what food can be brought with you on your Sun Country flight. This applies to food you are bringing from home through security. Once you get through security, you can bring just about any food on the plane that you buy at the airport.
Sun Country Carry-On Pet Policy
Sun Country Airlines allows Small dogs and cats may travel in the passenger section of the plane on flights within the U.S. 48.
Sun Country does not allow pets to be checked as baggage.
If you are going to bring a pet on board with you, it must be able to fit in a small, ventilated pet carrier that fits under the seat in front of you. Your pet carrier cannot exceed 16″ x 10″ x 8″.

Carry-On Pet Fees
Here is a chart showing the pet fees Sun Country charges each way. Double them for a round-trip flight.
To/From Destination | Pet Fee Each Way |
Pet Reservation Made in Advance | $ 75.00 |
Pet Reservation Made at Check-in | $100.00 |
A maximum of four pets are allowed per flight, and only one pet per ticketed traveler is allowed. Always make sure there is space for your pet when you purchase the tickets.
