Cinemark Theatres are again offering American Airlines miles for the purchase of a large soda.

Back in 2004 the offer was just 100 miles per soda. Now it appears that not all codes are winners, but at least 1 in 5 are and those receive a minimum of 500 miles and a long-shot chance for 100,000 miles.

Sounds great, right? Just go to a Cinemark theatre and dumpster dive for these codes off sodas and get some award tickets.

Alas there’s a limit of 10 Instant Win 500 AAdvantage miles Game Piece codes and two 5,000 AAdvantage miles Game Piece codes per account. Of course, each member of your family can have a separate account and I’m willing to bet that excess codes wind up on eBay…

Since there aren’t any Cinemark theatres near me I’ll consider writing in for game pieces:

For a free Game Piece, send a self-addressed stamped envelope in a business size (#10) envelope with first-class postage affixed, to: Cinemark/Coca-Cola Promotion Game Piece, 3900 Dallas Parkway, Suite 500, Plano, TX 75093, to be postmarked by September 1, 2006 and received by September 8, 2006. All requests must be handwritten. No mechanically reproduced requests permitted. Limit one request per outer envelope.
