re: Possible Capital One Venture One upgade to Venture?

I don't know about the waiver, but the Barclay card earns 2x on everything like the Cap One, however, any time you redeem points for travel you get 10% refunded, so you're effective rate is 2.2x on purchases. You also can do partial redemptions, while Cap One requires that you cover the whole expense with points. Lastly, Barclay card comes with TripIt Pro subscription which is like a $40 value.
