INFANT PASSENGER
An infant is a passenger who has not yet reached 2 years of age and is not occupying a seat. Infant passengers generally pays 10% of the applicable normal adult fare. International travel between Canada and Mexico includes infant travel, which is free of charge.
You may allow only one infant who is not occupying a seat to travel with an adult at such a discounted fare. If the adult passenger is travelling with more than one infant, the other infant needs pay a CHILD fare.
