Discover Southwest Airlines Unaccompanied Minor Policy  is an easy and safe way to travel for children aged 5-11. The fee for this service is $50 per way, with careful attention, as there will be a flight attendant dedicated to ensuring the child's safety while on board. Parents or guardians will have to take the child to the gate and pick up at the destination. Although the policy is comprehensive, it only applies to younger children, as minors aged 12-17 can travel alone without restrictions.
