Street poster: airline miles donation

An interesting sign caught my eye. I have recently been interested in how charity differs in modern society and in the Hasidic society, and I an going to go out on a limb and guess that this particular type of donation is unique to Hasidim. What is it? A collection of airline miles for the ill. Here’s some of the text:

“Your airline miles can save lives!”
“Donate your airline miles and use it to save lives.”

“Miles for life provides airline tickets and booking services to sick Jews and their caregivers who have to fly to hospitals in order to find their total cure.”
