As of July 2015, Sun Country Airlines charges no baggage fees for one carry-on bag and one personal item. Sun Country does charge checked baggage fees: $20 for the first bag and $30 for the second bag if paid online or $25 and $35, respectively, if paid at the airport.
To qualify as carry-on baggage, a bag must not exceed 24 inches in length, 16 inches in width and 11 inches in height. Personal items must not exceed 16 inches in length, 11 inches in width and 8 inches in height. Checked baggage is limited to items weighing less than 50 pounds and with an added length, width and height of no more than 62 inches. The fee for oversize or additional luggage is $75 per item.
In the event that passengers must unexpectedly check carry-on items at the gate due to a lack of overhead capacity on their flight, Sun Country Airlines charges no fees. Passengers can also have their first checked baggage fee waived if they have taken advantage of the airline's promotional first class upgrade, if they are a Sun Country Airline Visa cardholder, if they are an unaccompanied minor, or if they have purchased an international flight and hotel package through Sun Country Vacations. Similarly, passengers travelling through the Sun Country Groups Department are exempt from fees on their first and second pieces of luggage, along with Ufly ELITE members and first class passengers who did not purchase their ticket as an upgrade.
