One child over 14 days and under two (2) years of age, not occupying a seat, may be carried as a Lap Child when traveling with an adult (12 years of age or older). Although a boarding pass is not required for the infant, you will need a Boarding Verification Document.
A Lap Child may be carried free of charge domestically. For international travel, applicable government-imposed taxes and fees must be paid, and a ticket will be issued for each person, regardless of age.
