minimum age a child can fly alone
General Age Guidelines: Airline rules vary, but here's a good idea of what to expect on domestic flights: Children ages 1 - 4 may fly only when accompanied by an adult. A child must be at least 5 to fly alone. Kids ages 5 - 8 can take a direct flight to a single destination but not connecting flights. Those over 8 may change aircraft. If they're ages 8 - 11, they will be escorted by airline personnel to their connecting flight. A significant extra charge for this service is likely.
