Sorry if this was discussed before...

Just got a Chase Ink Plus business card.

Thinking of using it to book a car rental on an upcoming vacation. I've priced rentals and the UR site's Travel section has a super deal. But when it comes to payment, it insists on using the Ink card -- it won't let me substitute my personal cc (an AMEX). So the only way I can latch onto this deal (thru UR) is to pay for it with my Ink business card.

I read the card T&C, and while it does cover car rentals, there seems to be a difference between "business" and "personal use". I certainly couldn't justify this rental as "business", so it seems I might fall under the personal usage -- in nwhich case the cc coverage becomes Secondary, and I'd have to file with my own insurance first.

Has anyone any experience using a Business cc to pay for obviously personal expenses, esp iun regards to a car rental?

Thanks
Scott
