When signing up for AMEX you get free lounge passes - does anyone know if supplementary card holders can sign up and get lounge access to?

And - does anyone have any insider tips on any banks offering a credit card signup bonus in the near future?

Hi. Amex Airpoints Platinum Card holder.
For centurion lounge passes, the account gets TWO per calendar year. It can be used by either the primary cardholder or supplementary, no need for primary to be in attendance. Note TWO per account, NOT per card.
For Priority Pass TWO entries per membership period. Only the PRIMARY cardholder can apply for Priority pass.
There is no free guests for either option on the NZ Amex Airpts Platinum. You can always pay. Can’t remember the price off the top of my head, 60USD maybe it was?
Hope this helps.
