Air travel can be stressful for anyone, but it can be especially daunting for children traveling alone on long-haul flights. Air Canada understands this and has introduced a UMNR program to make traveling as smooth and safe as possible for kids who are traveling alone. Air Canada Unaccompanied Minor service is only available on specific routes or non-stop flights. Air Canada offers an unaccompanied minor (UM) service for children aged 8 and up who are traveling alone.
