Pietermaritzburg Airport is PZB and Windhoek Hosea Kutako Intl Airport is WDH. These codes are created by the International Air Transport Association (IATA) and airlines use them to identify the departing and arrival airports in the flight routes they service. This flight route has multiple associated airports, so we think it might be helpful to learn the name and codes of them as well. They are Windhoek Eros Airport (ERS).
