About Airlink
Airlink is a privately owned South African regional airline with its main base at O.R. Tambo International Airport in Johannesburg, plus operations from Cape Town and Durban. It specialises in routes that larger airlines tend to skip: smaller South African towns, safari gateways such as Hoedspruit and Skukuza, and cities across Southern and East Africa, including the remote island of St Helena. Airlink flies under its own 4Z code, is not in a global alliance, and has interline and codeshare agreements with many long-haul airlines, so its flights often form the last leg of an international ticket. It offers economy throughout and business class on its larger jets.
For safari and regional itineraries, search the full journey on IATA.co as well as the Airlink leg on its own. Airlink fares appear in your search results whenever our flight suppliers offer them for your route and dates. Fares are live in the booking portal and the flights API, and you pay from a prepaid balance.
Airlink airline codes explained
Airlink uses the two-letter IATA airline code 4Z and the three-letter ICAO code LNK. The IATA code 4Z is the one shown on tickets, fare displays and booking screens, while the ICAO code LNK is used in air traffic control and flight planning.
Airlink is a full-service carrier, based in South Africa, operating mainly from Johannesburg (JNB). It is not part of a global airline alliance.
Booking Airlink fares as a travel agent
Travel agents book Airlink fares on IATA.co without their own IATA accreditation. Activate an agency account, top up a prepaid balance, then search live 4Z fares in the booking portal: the price, baggage and fare rules are shown with each offer before you confirm, and the amount is deducted from your balance. Airlink results appear whenever our flight suppliers return them for your route and dates, so what you can book follows live supplier content rather than a direct airline deal.
Search Airlink (4Z) through the flights API
Developers and agencies can run the same Airlink search from their own site, app or back office through the IATA.co flights API. Filter a search by the carrier code 4Z and read the fares back as JSON, then book from the same prepaid balance. See the flights API and the API docs for the full reference.
