Wow! I no idea that supplemental cards in the US come at a fee. In the UK, there is no charge for either an additional Platinum or Centurion Card, With Centuriom you get two cards, an additional cardholder gets one, and you can have up to four other Platinum card holders, whicy are all free. all their expenditure goes on your monthy statement which you have to settle.
It would be good to see a comparative table of each country's costs, and card benefits for both Platinum and Centurion (USA, UK, Germany, Switzerland, Japan, Australia, are there any others?). Has this already been discussed on the site or should a new thread be created?
