Here’s the scoop on how to earn status on an alliance and not just an airline. The oneworld alliance may be smaller the other two major ones, but its 14 members (plus 21 affiliated members) can literally take you anywhere in the populated world.

If you regularly fly on Air Berlin, American Airlines, British Airways, Cathay Pacific, Qantas, Iberia, Finnair, Japan Airlines, LATAM Airlines, Malaysia Airlines, Qatar Airways, Royal Jordanian, S7 Airlines, or SriLankan Airlines, it’s a safe bet that you might benefit from oneworld tier status.

Who Is the Platinum Delta SkyMiles Credit Card From American Express Good For?

If you fly on Delta and are trying to reach or maintain elite status, the Delta SkyMiles^® Platinum American Express Card can be a great tool. This premium card offers a welcome bonus and allows you to earn Medallion Qualification Dollars (MQDs) that count toward elite status.

Although the Platinum Delta card does come with a higher annual fee than both the basic and Gold Delta SkyMiles cards, it offers a greater potential for earning miles, with a slightly higher welcome bonus, as well as the ability to earn more bonus miles if you spend more.
