First, we’ll begin with the consumer offers.  Essentially, the primary difference between these cards is the credit quality of the consumer.  Consumers with excellent credit can get a lower APR than those whose credit Capital One deems to be good.  However, the no hassle rewards offer is the same for both cards.  First, the cards offer 1.25 miles for every dollar spent, which allows you to earn miles 25% faster than with most standard airline rewards credit cards.  Second, the card allows you to use your miles on most airlines with no blackout dates and no seat restrictions.  Finally, both no hassle cards have no expiration dates on the miles you earn.  This is an important plus, as many frequent flyers have seen thousands of miles evaporate via the short term life of miles with many airlines. 

Businesses, like consumers, have more than one No Hassle Miles option.  There are, however, two distinctions.  The first is in the miles.  With the  Capital One® Business Platinum with No Hassle Miles(SM), one mile is earned for every dollar spent.  With the Capital One® Visa® Business Platinum with Double No Hassle Miles(SM), two miles are earned with every dollar spent.  Besides the mileage differences, the interest rate terms vary between cards, with the standard card offering a substantially lower APR.  However, businesses that pay their balances in full every month can benefit substantially with double miles on every purchase.
