I've seen the news reports that HAL are preparing to restart flights, but at the moment their main operational systems are not prepared for services. There are 11 BA flights inbound to LHR still in the system, most of them are LGW to LHR transfers for aircraft, which one would expect. There's at least one A380 due around the M25. But they aren't anything more than a plan at the moment and nothing due into LHR. For passenger departures to South Africa, I suspect that since BA have cancelled the services previously, there won't be many passengers on any services this evening.
