Thanks so much ...here is my spend patterns...

The $500,000 is not spent on gas, grocery, restaurant, or home impvmt. It is spent on equipment purchases. So, extra points for gas etc. are not valuable.

It would be great to have Elite Status upgrades, or access to Airline clubs for the vacations.

All credit card bills are paid on time.

Seems to me that unless the Airline cards offer double points then the Starwood is better.

How does Centurion or Chairman or Merrill+ offer benefits more than Starwood Amex?
