If you're interested in earning airmiles for donating money, as I think was the original question here, there's also eMiles.com.
1. Sign up with them for your preferred airline,
2. wait to receive an offer from a charity you like,
3. donate money (via credit card for more miles) & earn eMiles,
4. claim airline miles in 500 eMiles increments,
5. wait for miles to post to airline account, usually at the end of each calender month.
Takes awhile, but might be the only thing available, assuming you like the charities eMiles offers. Plus, you can do this all year long and not just during some short-term special offer.
