TRIO (Transplant Recipients International Organization). In their recent newsletter they had the following:
"TRIO is most fortunate to be one of only 20 organizations to allow frequent flyer seats for transplant-related travel at no cost. Do you or someone you know need to travel for pre- or post-transplant related medical visits? Does a transplant recipient or living donor need to travel with a care-giver? Please take advantage of this wonderful program, generously provided by United Airlines!"
The web link is as follows:
http://www.trioweb.org/communications/travelprogram.shtmlThe qualifying circumstances include: "Travel by organ donor for the purpose of donation or for medical consultation or treatment which is a prerequisite for donation."
Since this is supported by donation of frequent flyer miles, there is also information how to donate your miles for this cause.
Hope someone may find this of use.
