What are co-branded credit cards?

The Citi® / AAdvantage® Platinum Select® World Elite Mastercard®* is one of the best — if not the best — airline credit cards thanks to all that it offers, but you’d need to fly American Airlines fairly often to take full advantage of it. It comes with a $0 intro annual fee for the first year (and a $99 annual fee after that), and you’re eligible for a welcome bonus of 50,000 points after spending $2,500 within the first three months of card membership.

For rewards, you’ll earn 2X miles on eligible American Airlines purchases, 2X miles at gas stations and restaurants and 1X miles on all other eligible purchases. As for some of this card’s benefits, you’ll get your first checked bag free on domestic flights (for yourself and up to four companions traveling together on the same reservation), preferred boarding and 25 percent off eligible in-flight food and beverage purchases.
