Online check-in Interair South Africa - https://www.check-in.site

As of my knowledge cutoff in September 2021, Interair South Africa was a privately-owned airline based in Johannesburg, South Africa. It operated domestic and international flights primarily within Africa. However, please note that the aviation industry is subject to changes, and there may have been developments regarding Interair South Africa since then. I recommend checking with the latest sources or official websites for the most up-to-date information on the airline.
