US Airlines Travel Union Scottsdale Award notification lying mendacity falsehood unwanted-mail Scottsdale, Arizona

I got the same offer in the mail and called their number.  I talked to a telemarketing person who said that it's a promotional deal by a discount travel agency who is giving "free" tickets (actually, more like discounted because you have to pay some minimal admin costs plus taxes) in exchange for sitting through a sales presentation.  My guess is that they will  try to get me to sign up for a membership in their travel club or whatever, which I'm not planning to do.  In any case, so far, at least, I don't have any evidence that it's any more than a high pressure promotion.  If it turns out to be a scam, I'll write a rebuttal.  By the way, I'm generally skeptical, not ignorant or a sucker and I don't live in a poor neighborhood.
