Kids aged 5 to 11 traveling alone from Calgary to Fort Lauderdale are considered unaccompanied minors. If you have a child flying alone from Calgary to Fort Lauderdale, consider booking Southwest Airlines, which has a lower unaccompanied minor fee. The minor will be assigned a cabin crew member to supervise them throughout the journey. Since flights from YYC to FLL have stopovers, the child will be escorted and safely transferred between the connecting flights. Southwest Airlines also ensures the child gets priority boarding and is assisted with baggage.
