I finally applied for an American Express Brilliant card with 75k points offer after $3k in purchases. Also, I have an existing Marriott card with Chase (from 4 years ago) and received an offer to upgrade for two 35k certs on a single purchase. Reading the offer terms for the Brilliant card, it appears that I’m eligible to receive the 75k points since I had the other card for more that 24 months. Now the question is, am I able to upgrade my Chase card for the two cert offer? Will it affect my 75k offer from the Brilliant card? Thoughts? Thanks much!
