Amex Centurion card gets you second-from-top elite status on three or four carriers, including PM on DL. This is a by-invitation/recommendation-only card.

At present, AA awards lifetime gold or platinum status to members who reach 1mm or 2mm program miles, respectfully. You could in theory reach this requirement entirely through cc spend (or any source of miles) as at least one somewhat frequent poster here has done. Several people have strategies to get three Citi-AA cards at once which at present appear to net 75k each (225k in total). With these cards and some concentrated spend, you could reach lifetime elite status. (AA has made motions indicating that the "any source of miles" rules may be tightened in the future - but the head of their program said in a milepoint.com roundtable that existing million milers would be grandfathered.)


Amex Platinum is offering status on CX to cardholders from [Australia] at present.
