There are air policies for infants, if your kid is below 2 years old, then you don’t have to buy his/her ticket for the journey. And, above 12 years of age, anyone can carry one infant with them without paying any air ticket for the infant. But in case, you are on a round-trip, and during departure, your little is below two then you don’t have to buy the ticket. But in case, during the arrival, your little one is above 2, you have to buy a full ticket for your infant. Still, the policies are different for different airlines.
