The airline has so far operated five cargo-only flights from Shanghai to Heathrow, each carrying around 16 tonnes of medical equipment.
A sixth charter is due to arrive at Heathrow on Tuesday afternoon (21 April) thanks to special dispensation from the CAA, with two more flights planned later this month.
To maximise capacity, Virgin has been cleared to transport cargo in the cabin as well as the hold. In total, the eight flights will deliver more than 100 tonnes of PPE and other medical equipment.
