appleguru was responding to MSP, who was asking if the DL Plat Amex issued as a secondary card on a DL Reserve Amex account looked like the standalone DL Plat Amex that carries a $195 AF for the primary cardholder.

They do look exactly the same - like this. So much, in fact, that when I upgraded my DL Plat Amex to a DL Reserve Amex, they didn't even send Mrs. Lee a new secondary DL Plat Amex card. She's still using her old one.
