Before heading to the airport, familiarize yourself with Sun Country Airlines Baggage Policy to avoid extra charges. Passengers are allowed one free personal item, but carry-on and checked baggage require fees. The airline has strict weight and dimension requirements, especially for checked luggage. Paying for baggage online ahead of time is cheaper than doing it at the airport. Sun Country also has clear rules for special items like sports equipment or strollers. Reviewing the baggage rules ahead of time ensures a smoother check-in process. Always double-check current fees and regulations on Sun Country’s website for the latest updates.
