Discover Southwest Airlines Unaccompanied Minor Policy is widely deemed to give the juvenile flyer a safe and hassle-free flying experience. This added service for kids aged between 5 and 11 years requires payment of $50 each way. Southwest is sure of individualized care by setting up a specially assigned flight attendant who keeps an eye on the child during the whole trip. The policy states that an adult must collect a child from the gate only after he or she has been escorted there. In the case of minors from 12 to 17 years, who are capable enough to fly alone, they are exempted from this practice, however.
