re: Traveling to and from MD Anderson

best of luck with this, two things I would look into is contacting someone in sales at SW, explain your situation and see if they will work out some sort of discounted plan, they're pretty philanthropic over there, wouldn't hurt to ask, also there is an organization of business aircraft owners that donate time on their planes for this type of situation, I'll try to find some sites and get back

ETA: start with corporate angels and NBAA charities
