The American Express Centurion card isn’t completely moribund. While they’ve consistently increased costs (recently adding a $5000 initiation fee on top of the $2500 annual fee), they’ve also been letting benefits lapse — no more Starwood Platinum status, no more Hyatt Diamond (replacing it with almost useless Priority Club Platinum), all the while the Membership Rewards program has been letting its best partners depart.
Finally a bit of good news. Plenty of Black Card holders report that they’ve been upgraded to Platinum status with USAirways (the previous benefit was Gold). Prior to the America West merger, Centurion members had status one level beneath the highest – Gold. After the merger the Dividend Miles program introduced four levels, and Gold was second from bottom. So they’ve finally fixed matters, Platinum being once again second from top.
