I got the impression on another forum that applying for 1 personal card and 1 business card at the same time will result in 2 HP; whereas 2 personal apps on the same day will only result in 1 HP. Is this correct?
Also, I read on a blog that when churning this card, we should leave the FF number blank, then later call to combine the accounts. Is this still true? Does this apply to getting a personal and a biz card, or just 2 personal?
