Still learning the best ways to maximize miles. I want to book a package through orbitz that includes a AA flight.
If I use my Citi/AA card will I get double miles since its a AA flight or do I need to book through aa.com. I also have a AMEX Plat card. Will this give me double points on orbitz travel purchases?

What is the best way to maximize the points when buying off sites like expedia and orbitz?
