I checked in my aunt this AM at PDX, and her BP on the PDX-ORD flight printed with Pre-Check on top. I didn't enroll her and neither did she, and we were wondering how she got it. (Not complaining, since she hit the shorter line, with her shoes and laptop in bag). She just did apply for the Chase United card, and she has an INK Bold...but I dont think thats one of the perks of these cards. Anyone have any ideas?
