I'm going to post an unpopular opinion (what else is new) that the code should remain in this thread. It'll be posted somewhere else, and now the world's premier frequent flier bulletin board (or whatever) won't have it. While this is a worthwhile charity and everyone should donate to the charity of their choice, I see all sorts of airline secrets being posted here and everywhere, don't see why this is any different.
In any case, thanks to OP for pointing out the opportunity.
