An infant is defined as a child under 2 years old. A search that includes infants assumes that the infant will be on the lap of an accompanying adult. This means that no seat is reserved for the infant. Generally, airlines do not charge for infants on lap. The average price displayed in the search results applies to the adults and children in the search and does not apply to the infant. However, when you are transferred by Yahoo! FareChase to the travel provider to [localize_finalize/] your booking, the information for the infant is also transferred and is reflected on your confirmation page of the travel provider. If you would like to reserve a separate seat for your infant, we suggest that you contact the airline directly.
A children's ticket is generally for those aged 2 to 11 although this does vary by airline. If in doubt, we suggest that you contact the airline directly for the fare rules for children's tickets.
