Hey, I am Elina Smith and I'm a traveller. And a question that everyone asks: What is Aer Lingus Unaccompanied Minor Policy? Guidelines for youngsters traveling alone are provided under Aer Lingus's Unaccompanied Minor Policy. Children under 12 must travel with an adult 16 years of age or older because the airline does not currently offer an unaccompanied minor service. Young passengers (12–15 years old) may, however, fly alone provided a parent or legal guardian goes with them to the departure gate and makes arrangements for a pickup when they get there. Minors travel safely thanks to safety precautions, although there might not be as many extra amenities available.
