You can do good with your airline frequent flyer miles. Through airline programs, nonprofit charities can use donated frequent flyer miles to provide flights for people who need to travel for medical reasons, for disaster volunteer assignments, and for special veterans' programs. Most of the major airlines partner with charities to put those unused frequent flyer miles to work.
Delta Air Lines - Under the carrier's SkyMiles program is Skywish Miles. The initiative connects frequent travelers with 15 nonprofit organizations that serve ill or wounded service members and veterans undergoing medical treatment, volunteers building affordable housing across the globe, children with life-threatening medical conditions needing specialty hospital care, and volunteers assisting with disaster relief and recovery. Charities supported by the airline's program include the American Cancer Society, Hero Miles (to help wounded veterans), Habitat for Humanity, and the Make A Wish Foundation.
American Airlines - The AAdvantage program allows travelers to donate miles to American Airlines Kids in Need to help support organizations that provide kids with medical, educational and social services.
