Can someone please share the application form?
When i called i was told no we dont do companion cards anymore.
You might want to hold fire until tizey reports back, if they said that they don't do companion cards any more, there's a chance you might take a hit in credit check for nothing, as they do run a credit check on you before giving you the Platinum Reserve.
I am hoping it isn't a new 2018 policy, the Platinum Charge card has undergone fair few devaluation already and I don't know how they could justify a $1200 annual fee on the card if they take away the Platinum Reserve. ($1200-$300 travel credit = $900, and $900 for Hotel gold status + Priority Pass is just too much imo)
