If you’ve mastered the art of using airline loyalty programs, it’s time to consider donating those frequent-flyer miles to a worthy cause.

Seventy-five percent of the 14,000 wishes granted annually by the Make-A-Wish Foundation, which helps sick kids achieve dreams like going on a safari or hunting bugs in Panama, involve some kind of travel, and now the non-profit is hoping to harness the estimated 16 trillion airline miles that go unused every year to help grant wishes.

Over the course of this month alone, travelers have given enough miles to fill two whole planes—that’s 282 total seats—with wish recipients, but there’s still time left to donate. The campaign ends today, so consider this your last call.
