No, Ryanair has a strict policy that does not permit children under the age of 16 to fly alone. Unlike legacy carriers like British Airways or Lufthansa, Ryanair does not offer an Unaccompanied Minor (UM) service, meaning they do not provide staff supervision, escorting, or handover procedures for children. Every passenger under 16 must be accompanied by an adult who is at least 18 years old on the same booking. If a child under 16 is found to be traveling alone at the airport, they will be denied boarding. This policy is part of Ryanair's low-cost operational model, designed to minimize liability and staffing complexity. For teenagers aged 16 and 17, Ryanair allows them to fly unaccompanied as adults, though they are responsible for their own documentation and navigation through the airport. Parents seeking to send a younger child across Europe must look to alternative airlines that specifically offer supervised UM services for a fee.
