The deal 10K miles for 1K donation looks pretty good to me. If you assume a 25% tax saving from the deduction, it comes to 0.0755 cents per mile. It is generally accepted (though often debated) that a mile is worth about 2 cents. Tese other deals do not look good at over 2 cents per mile.

BJJ, I think that your math is off - - it is more like 7.5 cents per mile. And take a look at the Starwood thread -- there are some ideas using Starwood combination miles/hotel awards that are decent.
