an62 the source article linked above notes that Amex Platinum access to Virgin Atlantic Clubhouses is limited to the Johannesburg and US locations. More importantly, it notes that these locations are operated by Plaza Premium and not VA. Amex Platinum has access to Plaza Premium lounges by virtue of the Global Lounge Collection benefit. Unless Plaza Premium assumes operation of the LHR lounge then, for the time being, Amex Platinum will not have access there.
