Baggage fees
No reliable fixed price is listed here. Check your booking for the cost of adding a bag; an unlisted price does not mean it is free.
Official baggage policyHow to use this policy
Check cabin bag dimensions, weight and personal-item limits separately. A bag has to pass every published limit at once; being under the length and width limit does not help if the depth, weight, or fare-specific allowance is tighter.
Editorial signal only. Leave margin instead of relying on discretionary gate behavior.
Sun Country Airlines liquids policy
At TSA checkpoints, ordinary liquids use containers up to 3.4 oz/100 ml within one quart-sized clear resealable bag per passenger. Medically necessary liquids have exceptions and must be presented for screening. Confirm departure/transit rules outside the US.
Family & Infants
Infant (under 2)
The contract permits one lap child per ticketed adult, starting at 8 days of age, under its age/seat conditions. Cabin items count within the adult allowance. Confirm booking eligibility and any international taxes; no separate ordinary baggage allowance established.
Stroller
Strollers can travel as checked baggage without an additional charge. Protect and package them properly; no universal gate-handover or jet-bridge-return guarantee is established.
Car seat
Free checked carriage. Cabin use requires a purchased child seat next to the guardian and an approved restraint that can be secured with the aircraft seat belt; confirm acceptance before travel.
