I agree with usoftie. The airlines just aren't this organized. I think it is a coincidence that you got something you were interested in. You probably could have just as easily received tickets to a tractor pull. Luck of the draw.

When I worked for DL, the talk was just beginning of "customizing" passenger's FF accounts. As I was on my way out, we just started to gather birthdates. Eventually, I think the intention was to store lots of information so that the agent booking the flights could say something like, "And would you like to have the hot seafood meal again?" I'm not sure how far DL or other airlines have gotten with this.

But, I think the airlines should really concentrate on the basics first without getting ahead of themselves.
