Can A Minor Travel With A Flightattendant?

Can A Minor Travel With A Flightattendant? Children younger than 5 can’t travel as unaccompanied minors, even if they’re flying with an older unaccompanied child. Young adults ages 15-17 can travel alone on any United- or United Express®-operated flight, or they can choose to opt in to our unaccompanied minor service. Can minors fly together?
