"Unaccompanied children" refers to children between the ages of 5 and 12 who come on board without being accompanied by an adult. This service has been specially introduced and extended by the civil aviation authority in recent years to help children of certain ages board alone. Since its launch, China’s major airlines have safely delivered tens of thousands of eligible children, greatly supporting parents who are unable to leave their job responsibilities. Parents can now save on travel costs and this service has been greatly appreciated by our customers. Every winter and summer vacation, a unique feature onboard involves large numbers of young passengers with signs attached to them.
