My wife is chairing the annual charity auction for our public elementary school and I had the dumb idea of getting parents with miles to donate to a fund that could be exchanged for a trip somewhere. After searching a few airline sites it appears that they restrict giving to only a few charities that they have chosen. Has anyone else tried to set something like this up that could offer some advice? Also, does anyone know if the hotel programs work the same way? I searched at Starwood and Hilton but could not find anything on their pages. Thanks in advance for the advice.
