AZ TUN-JNB rtn business £994.00
Not seen these fares for a while but AZ are just sub £1k for TUN-FCO-JNB rtn in business at the moment for selected dates. I was looking at 15 October outbound and return 4 November on Skyscanner - book through MyTrips OTA (there is a £988 fare with GotoGate but they get terrible reviews). As usual with AZ booking too far out you pays your money and takes your chances!
