Currently the only international flights allowed within lockdown level 3 are repatriation flights. These are not commercial flights. Rather, all the complex logistics are organised through the Department of International Relations and are aimed at repatriating foreign citizens and South Africans only.
Passengers on these flights have to prove their bona fide repatriation requirements and all their documentation, health checks and quarantine, as well as the destinations serviced, are tightly controlled by the governments of South Africa and corresponding destinations.
These policies have been established by the South African Government as part of its Risk-Adjusted Strategy aimed at curbing the spread of COVID-19. The repatriation flights are therefore not open for booking by any intermediaries, including travel agent.
