Last year I went to a conference and met an American Express guy. To make a long story short, he was telling me Amex (and other credit card companies) also sells information to 3rd parties. For example, you like Italian food (they can tell by multiple purchases in Italian restaurants) and fly on Airline X? The airline might be interested in that data, so it could change its food offering on the plane. This is just ONE example.... So, I'm not surprised.
