Amex platinum business plaza premium lounge

[Janusjiang]

Hi all,

Does anyone know whether the supplementary cardholder of an Amex platinum business would give you access to the Plaza Premium lounge? I can't find it anywhere in the T&Cs of the business card although the T&C's of personal card do mention about access to the Plaza Premium lounge

Supp holders of the personal Amex Plat charge cards get access to Plaza Premium lounges. I'd imagine it would be the same but I don't really know for sure.
