Decided to apply since this card is going away and see this to the right of the application:
Welcome offer not available to applicants who have or have had The Marriott Rewards®Premier Credit Card from Chase, The Marriott Rewards® Premier Plus Credit Card from Chase, The Marriott Rewards Credit Card from Chase, or The Ritz-Carlton Rewards®Credit Card from JP Morgan in the last 30 days.
This is the first I've remembered seeing one bank not offering a bonus due to your relationship with another bank (outside of 5/24.) Sure enough, I do have the Ritz Carlton Rewards Card and when I click submit on my application I receive:
NAME because you have or have had a Marriott or Ritz-Carlton Consumer Co-Branded Credit Card issued by JP Morgan Chase, you are not eligible to receive the welcome offer.
Seems pretty cut and dry that I'm not eligible...... right?
