Twice a year NFCR offers a bonus greater than the standard 10 miles per dollar. I believe they have one in effect until Dec 31. I suggest calling if interested. The tax letter you receive will specify the value of the miles received so the entire donation amount will not be tax deductible. More information, including POC at NFCR, about miles for charitable contributions here:

Donating miles directly to a charity is different.
BTW, a couple of weeks ago I received an email from the NFCR POC which stated: “Hi xxx - we just re-negotiated our contract with AA and they have increased our mileage cap from 500,000 to 1 million miles per rolling year per AA account. Spread the word to any buddies who may be planning a big trip in the future.” (I had previously discussed with her the LT AA status changes that occurred on Dec 1. I wonder how much NFCR donations will change now that other charities are also offering 10 miles per dollar (previously the others offered 5) and now that the miles will not count toward LT status.)
