American Airlines Remembers Me

Oh thanks goodness, someone is still thinking about automated telephone interfaces!  I just got an email from American Airlines informing me that from now (pending some action on my part) they will recognize me when I call.  If you are an American Airlines Advantage (reward card) holder you can now register your cell phone number with your account and when you call from that number they will recognize your number pull up your details without you having to enter account numbers, etc.  If you call within 23 hours of a scheduled flight they will automatically provide you with details specific to your departure.  And here I was thinking that my parents were the last people to get caller ID!
