If you have reward points you haven't used (and maybe never will) then give them away to charity. Many travel companies are already getting involved in the Haiti relief efforts and we thank them for that.
Air Canada - Donate Aeroplan Miles to the Red Cross or to Médecins sans Frontières.
Continental Airlines allow transfer to a number of charities but right now it's probably best to donate your OnePass miles to the American Red Cross or AmeriCares.
Delta Airlines - Donate SkyMiles through the SkyWish program.
United Airlines - Mileage Plus donations go to the American Red Cross. Choose from 2,500 to 90,00 miles to donate.
US Airways - Donate your Dividend Miles through the Miles of Hope program.
You can also earn air miles by donating hard cash.
American Airlines - AAdvantage members can earn a one-time award (until February 28th, 2010) of 250 bonus miles for a minimum $50 donation, or 500 bonus miles for a donation of $100 or more to the American Red Cross. Donate!
Spirit Airlines - The first 200,000 people to make a donation of $5 or more to Yele, UNICEF or the American Red Cross - through Spirit Air (until January 17th, 2010) receive 5,000 bonus miles.
Auto Europe - Pledges $5 per reservation booked by any US travel agent, for their clients through March 31st, 2010 (for travel through June of 2010). Auto Europe CEO, Imad Khalidi, vows to personally match the plege.

Marriott International - The Mariott Hotels in Puerto Rico and Dominican Republic are being used as staging areas for the relief efforts in Haiti and the Marriott Foundation is sending $500,000 to the Red Cross Haiti Relief and Development Fund (audio).
The more Marriott Reward points you offer, the larger the Mariott Cheque to the American Red Cross: 18,000 points for $50; 33,000 points for $100; 60,000 points for $250; and 180,000 points for $1,000. Awesome!
