World Mastercard - anyone have a summary of the benefits included?

My Westpac Altitude Black CC is a “world Mastercard”…there are apparently “benefits” attaching to the M/C World status. I know about the Starwood Gold status, but haven’t worked out how to access it yet. However I am looking for a summary/list of other “World Mastercard” benefits etc. Does anyone have information?

Have a look at our guide to SPG Gold via World Mastercard here and the general World Mastercard site here.

Thanks Keith, I appreciate the follow up.

I followed through and it looks like this one night gold upgrade offer has expired, apparently, July 14. It was still on offer when I applied for the Altitude card, and I don’t remember an expiry date. Pity, a great deal as I’m planning about 10 nights in a sheraton, and Gold from day 1 would be fantastic!
