Just came across a new opportunity for mileage collection which I haven't seen posted yet. The A. F. Daihy Foundation (which promotes organ donation awareness) is offering "miles credited any United States based airline frequent flier program" in exchange for signing up for organ donation. The offer has two components. You can get 750 miles simply for signing up as an organ donor. I don't think you have to sign up specifically for this deal, they just want you to submit "proof of organ donor status" by fax or email. Although they don't provide any details about what constitutes "proof", I'm thinking that this might be a photo-copy of your driver's license if that indicates organ donor status in your state. It might even be possible to sign up several times if you're an organ donor in different states although this may not be moral and could possibly create a situation in which, for example, they believe you owe them 14 kidneys or something. The more lucrative offer is if you actually wind up donating an organ. The web site specifically mentions that "live or cadaver donations" qualify. When you register, you provide both your own mileage program information and that of a beneficiary, so apparently in the event of a cadaverous donation the miles go directly to your named beneficiary. The offer is 50,000 miles for the first organ and 25,000 miles for each additional organ. So two kidneys, two eyes, heart, liver, and both lungs would earn you (or, really, your beneficiary) 225,000 miles! Obviously, no one likes to think about being in a position to be an organ donor, but this is an opportunity to leave your family in a really advantageous mile situation in the unthinkable does occur.
