Can a flight booking API handle bookings for children and infants travelling with adults?

Yes, a flight booking API can usually handle children and infants travelling with adults. The search can use each passenger's age and date of birth to request the correct fare category, then return suitable flight options for the whole party. The booking details must be entered carefully because airline rules are based on the child's age on the travel date.

The available choices depend on the airline and the flight supplier. An infant may need to travel on an adult's lap, while a separate seat may be required or allowed in other cases. Some airlines also limit how many infants can travel with one adult. The fare, taxes, baggage allowance and seating options can differ for adults, children and infants, so these details should be shown clearly before payment.

Not every supplier returns the same information or supports every request through its API. Services such as adding an infant after a booking has been made, requesting a cot or choosing nearby seats may need separate airline confirmation. The API should not treat these requests as guaranteed unless the airline has confirmed them.

Before offering these bookings, check which passenger types your chosen flight suppliers support, what information they require and how special requests are handled after booking.
