Donate your airline miles during Wishes In Flight and make a child's wish come true! Air travel is Make-A-Wish® Idaho's biggest annual expense. In fact, more than 93% of the wishes we grant involve air transportation. At the same time, literally trillions of airline miles go unused each year. Instead of letting those miles expire, you can put your unused Delta, United, or Horizon/Alaska miles to good use! On March 21, 2018 call in to KBOI channel 2 at (208) 472-2220 and donate your miles as part of our on air telethon from 5am-10:30pm. You may also donate your miles by mail to 310 W. Idaho St. Boise, ID 83702 or click above to donate online!
