Children under 5 years of age may not travel alone under any circumstances. Another passenger at least 16 years of age must accompany them. Seaborne reserves the right to request documented proof of age for the adolescent accompanying a child under the age of 16.

Infants under 2 years of age who travel Puerto Rico and the U.S. Virgin Islands may be held in an adult’s lap at no charge. For International travel, children under two years of age are required to have a ticket in their name for 10% of the applicable adult fare for the International portion. A 10% ticket does not entitle infants to their own seats. Contact Reservations for more details.
