Capital One made its Venture and Sparks Miles cards more valuable when it added the ability for cardholders to transfer the miles they earn to 15 partner airlines at a 2:1.5 - 2:1 ratio. For those with no loyalty to one hotel, the chance to earn 10x miles when booking rooms at hotels.com/Venture through January 2020 is a great perk. The flat miles and cash back earned on Capital One Venture, Miles and Quicksilver cards makes things simple for cardholders, since you don't have to worry about remembering which spending categories offer higher rewards. If you spend regularly on dining an entertainment, the 4% cash back on the Savor card is a good deal. The new 5x for hotels and rental cars booked through Capital One Travel offered by the Spark Miles from Capital One card are really helpful for businesses that spend regularly in these categories. Finally, you have to love the extremely generous sign-up points and cash back currently being offered by the Spark Miles and Spark Cash cards, respectively.
