No, you still need to meet the same requirements for elite status.So is holding the SPG biz card the same 'perk' (maybe) as gold status? i.e. upgrade room if available?
For Gold status, even with Amex SPG Business card, you will need to have a minimum $30,000 spend on the card in a calendar year, or:
In order to become a "Gold Preferred Guest", an SPG Member must have at least 10 Eligible Stays or 25 Eligible Nights in a Qualifying Period at SPG Participating Hotels or SPG Partner Hotels (the "Gold Minimum Requirement"). The Gold Minimum Requirement must be achieved in the subsequent Qualifying Period to remain a Gold Preferred Guest during the calendar year following such subsequent Qualifying Period or the SPG Member will be downgraded to the Preferred Guest level on March 1st of the calendar year following such subsequent Qualifying Period. If an SPG Member earns more than 10 Eligible Stays or 25 Eligible Nights in a Qualifying Period, he/she will not earn more than one Eligible Status Year.
