From US inflight magazine Attache'

As an additional way of offering redemption options for our Dividend Miles members, we began offering the popular Miles for Magazines program in 1997. Although we occasionally advertise this service through direct mail, members interested in using Dividend Miles for subscriptions can do so anytime by calling 1-800-586-9632. Finally, it does typically take four to eight weeks to get your first magazine, depending on the publishing schedule for the magazine you select.
