Following the Boeing 747-400 technical issue at Cape Town yesterday, British Airways Boeing 747-436 G-CIVA, which arrived into Johannesburg as BA57 from London Heathrow (depart London Heathrow 12th February) this morning, positioned Johannesburg – Cape Town as BA9253 this evening in order to operate yesterday’s delayed BA42 Cape Town – London Heathrow as BA42X. As a result BA54 Johannesburg – London Heathrow was cancelled.
