Oh, and the gift cards I remember were not for a dollar amount, but for specific items. Perhaps that's a better clue. For most of my trips in the 1990's (say 1992 - 1999) when I flew FC, I got Tiffany cards that were good for specific items like vases ( I got tons of these!), leather bound maps, curio boxes, etc. and not for a $ amount. And another selection of "better" items for two coupons. Anyone remember $ amount of thank-you cards???
