This is inaccurate. If your wife orders a Supplementary Platinum card ($175/yr), you will receive every benefit including lounge access. The $200 airline fee reimbursement benefit is shared across all cards on the account, it's $200 per account not $200 per card.
Wow, I didn't know that... that would be perfect. Does that mean that the American Express points would belong to us jointly and could be transferred to a mileage program in either of our names?
Thank you,
