If you are gold you could "buy up" to Platnium if you got the Am Ex reserve card and charged $60K. Or if you have at least 55K miles as a gold, get the platnium and charge $50K.
I basically am able to go from gold to PM with $50K spending on my Platnium Delta Am Ex which is only $150 a year. I figure my paid SC status is being diluted thanks to the Plat. am ex so I don't feel bad getitng a higher status with my delta am ex.
