You'd be better off to upgrade the Plat to the QS. Which you could check now since you've had it for 7 months already here: https://verified.capitalone.com/sic-ui/#/esignin?Product=Card&Action=ProductUpgrade Then take the QS1 with the annual $39 fee and combine right before the year is up and a new $39 fee is charged which will then close it out. Then you'll get the 1.5% cash back on the QS and no annual fee at all. If your upgraded then you'll have two 1.5% cash back cards for now.
