So I just tried to apply for the Hilton business card, which I've never had before. I got the pop-up saying I wouldn't be eligible for the bonus... but I can't tell why. I have the regular Hilton card, and I upgraded it to the surpass ( and then back to the regular) last year, but I haven't applied for any new cards from Amex in 2 years. Any ideas? Would it make a difference if I apply from an private browser window without logging into my account?
