I have had the AmEx Platinum for a year and having recently renewed it (no luck with retention offers!) took up the Business Platinum offer too.
So far, I have been unable to link both to app because of different names. But I wanted to confirm - will I get those benefits like dining and travel credit/Priority pass/newspaper/prime/Accor etc a second time with the Business card? And if so, can I use a different email to pass to a friend?
Also, I can't see where to change the terms of referral offer on that link, looks like they are now offering 300,000 to referee, pretty good!
Thanks

two separate cards / accounts should yield two separate benefits.
