What is a Lapchild defined as in air travel?

In air travel, a Lapchild is defined as a child under the age of 2 who doesn't have a ticket. This designation allows infants to travel by sitting on a guardian's lap rather than occupying a separate seat. Airlines typically permit this arrangement, sometimes requiring that the child be at least a certain age to ensure safety and comfort, as well as to comply with regulations regarding child passengers. This status is distinct from other categories of child fares, which may apply to older children who require their own tickets and seats.

Children who are over the age of 2 generally need to have their own ticket for travel, while those traveling with a guardian are typically considered minors needing specific arrangements, but they don’t fall under the definition of a Lapchild as understood in airline policies.
