Don't forget
golf!
Other than golf and the $250 air travel credit (automatic?), I think you've hit on the high points. I too need to get set up on the car rental memberships.
I assume you've setup a web login and alerting?
I tried using Virtual Account Numbers (VAN) with an Citibank online account just associated with the credit card, was unsuccessful. Once I associated the Prestige card with an existing "online banking" account, the card was added to the list usable in VAN.
