What are the rules for minors flying alone in KLM?

If children are aged 5 to 14 years, then they can fly alone. But 15- to 17-year-olds can travel alone according to the KLM Unaccompanied Minor Policy. Under 5 years old cannot fly. Parents or guardians must stay at the airport until the flight departs, and the receiving adult must provide a photo ID to pick up the child..
