The other possibility is an American Express Centurion card, but it exceeds your stated budget and you cannot apply, you must be invited. It is generally believed that the minimum spend to elicit an invitation is between $250,000 - $500,000 per year. Centurion includes automatic Delta and US Airways Platinum status, and other benefits. There is a $5,000 initiation fee, and the annual fee is $2,500.
Damn. But I suppose somebody who has a $250k+ in annual Amex spending may very well already have earned elite status on one/many carriers.
