I've had similar issues with Chase. Credit score over 790, charge about $1 million per year on my cards and pay them off in full every month. I've been turned down twice for the Marriott business card. No problem adding the Ink Bold and the United Club card which is now my primary card but for some reason they won't give me a Marriott business card. By the way if you charge over $20k a month and fly United, get the Club card.
