Children are defined as travelers aged 2 through 17, however individual airlines have their own rules and age classifications for defining children and adults. Child pricing may not apply to the airline or route that you are searching for if the selected airline views the travelers age as an adult.
Many airlines welcome unaccompanied minors on their flights, however tickets for infants under age 2 or unaccompanied children under age 18 may not be purchased online if the selected airline does not allow it. If you are booking a trip for an infant or a child under 18 years of age, traveling alone, without an Adult, we suggest you to call the airline directly or ask for assistance as certain airlines have restrictions on such travelers.
