Would you like to learn more about Southwest Flight unaccompanied minors policy? Children under the age of five who are travelling alone, in another cabin with their parents or guardians, or sharing a flight with another kid are covered under the Southwest Flight Delay Compensation. Minors older than 12 and up to 16 years old can also take advantage of this service, while it is not necessary for them. AnSun Country  will be in charge of assisting the minors who are enrolled under this programme with the security and check-in processes. When boarding, they are given priority as well.
