Spirit Airlines Unaccompanied Minor Policy Spirit Airlines has a well-defined policy for the travel of unaccompanied minors on their flights. This policy is designed to ensure the safety and comfort of children traveling without a responsible adult companion. According to the Spirit Airlines Unaccompanied Minor Policy, children aged 5 to 14 years old are eligible to travel alone on Spirit flights. Children under the age of 5 are not permitted to travel unaccompanied. The policy requires that a responsible adult (aged 18 or older) must accompany the child to the departure gate and remain until the flight has departed, as well as meet the child at the arrival gate.For more Information https://www.flightyo.com/blog/spirit-airlines-unaccompanied-minor-policy/
