Because American Airlines is pretty tight-lipped about the program, it’s impossible to know exactly how many people are in the Concierge Key program. However, an Instagram post by a chocolatier in early 2019 shared an order of 11,300 boxes of hand-painted chocolates designed for Concierge Key members. Of course, it’s hard to say whether all members received the boxes, and some estimates by experienced travel bloggers go as high as 15,000.
