You're no doubt thinking of the Citi Gold / AAdvantage World MasterCard, the airline credit card Citi operates in partnership with American Airlines. Like other "legacy" airlines, American has overhauled its loyalty program to better compete with discount carriers.
To answer your first question, the Citi Gold / AAdvantage World MasterCard earns traditional frequent flyer miles in the country's oldest airline loyalty program. George Clooney's character in the feature film "Up in the Air" even spoke about how he used his own airline credit cards to reach ten million miles. While you probably won't hit that mark, you can earn plenty of extra miles that you can use for a variety of exceptional travel experiences.
Redeeming your AAdvantage Miles
Your second question has an even easier answer. Yes, you can trade AAdvantage miles earned from your MasterCard for tickets in Economy Class, Business Class, or First Class. Stay within the continental United States, and your coach ticket will only require 12,500 miles each way. Earn Elite status on American, and you can even participate in Dynamic Air Awards, a new reward marketplace where reward levels flex based on flier demand. Even though American has one of the world's biggest travel networks, you can still trade your points for seats on any of the carrier's network partners, giving you maximum travel flexibility.
Bonus offers for Citi Gold cardholders
At this writing, new Citi Gold / AAdvantage World MasterCard cardholders can earn a bonus award after making $750 in purchases during the first three months with the card.
Stretching your AAdvantage Miles
I know you're most concerned about earning airline miles, but the Citi Gold / AAdvantage World MasterCard can help you earn some other nice rewards. If you're looking to save money on your hotel stay or your car rental during your next vacation, you can trade some of your AAdvantage miles win you book reservations at AA.com. The points.com marketplace allows you to swap your miles for gift cards at popular retailers, like Amazon.com and Best Buy. Even though many travel rewards cards tout their ability to let you use points on any airline, American's loyalty program offers enough flexibility to make you consider staying true to just one carrier.
