No, a 14-year-old cannot fly alone with Ryanair, as the airline has one of the strictest age policies for independent travel in Europe. Ryanair does not allow anyone under the age of 16 to travel unaccompanied. Furthermore, the airline does not provide an "Unaccompanied Minor" (UM) service, nor does it offer any form of special assistance for young travelers. Every passenger under 16 must be accompanied by an adult who is at least 18 years old and is booked on the same flight reservation. If a minor is not on the same reservation as their adult companion, the reservations must be linked through the airline's customer service at least 4 hours before departure for a fee. If a 14-year-old arrives at the airport without a booked companion aged 18 or older, they will be denied boarding. This policy is strictly enforced and applies to all Ryanair flights, regardless of whether they are domestic or international.
