I applied for the Chase Ink Plus Visa last month after already having the Chase Ink Plus MC. The statement just closed after I met my 5k spent and I saw the 50k points already in my account. It has only been about an hour after the statement closed.

I called into the main line and got transferred to the business cards line. Since I was just approved a few minutes ago, she was having a hard time finding my card. Eventually she found my card and she confirmed that the 50k bonus points was linked to my new Chase Ink Visa card, even though I already have both Chase Ink Plus MC and Chase Ink Bold MC!
