Use American Airlines (of course!) and other elite-qualifying carriers to maximize your earnings. These elite carriers are Aer Lingus, British Airways, Cathay Pacific, Finnair, Iberia, LAN, Qantas and Alaska Airlines (and their eligible affiliates). When you earn miles on AA or on these carriers, you also earn points. Only points count toward your Challenge. (But remember that there are some fares on these carriers that are not eligible to earn miles or points. You can easily check out these rules on

And please note: For Challenges that start on January 1, 2007 and later, only points earned on American Airlines, American Eagle and AmericanConnection flights (including AA codeshare flights operated by other carriers) will count toward Challenges.
