General Age Guidelines for Flights

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. Older kids -- ages 12 through 15 -- may not be routinely escorted, but you can request this assistance.

Anyone under the age of 17 who is flying alone on an international flight must have a signed note from a parent or responsible adult giving permission, destination and length of stay.

Minors must be met at the destination by another parent or responsible adult.

Editor's Note: As these guidelines vary slightly by airline, be sure to contact your carrier for specific information.

Other Considerations

Although many airlines offer discounts for minors under normal circumstances, if your child is flying unaccompanied, it is practically a certainty that you will pay a full adult price for the ticket. The good news? The fee you pay for an escort covers an unlimited number of children traveling in the same party (except on Alaska Airlines, which will charge for more than three children). Hence, if you are sending your three children together, you pay only once. On international flights, the age restrictions are more stringent. Additional fees may apply if a flight is longer than six hours in duration.

Due to new post-9/11 security measures, you won't be able to accompany your child to the boarding gate. The airline will provide an attendant to escort your child through security and accompany them through the boarding process. Policies vary by airport, so be sure to check ahead of time if this is a concern. Special arrangements may be made.
