Only infants can be added to an existing booking by contacting our Customer Support Team. Any other passenger type will be issued on a separate booking. If you want to issue a ticket for a child that is traveling accompanied by adults on a different reservation you should select an adult as passenger type and insert a fictive date of birth as you can`t book without an adult on the ticket. After confirmation you can contact us through the contact form and provide both booking codes and correct date of birth for the child so we can update the booking.
