Also, www.aa.com has all this kind of basic info:

"You may use your miles for yourself or for anyone you designate** at the time of ticketing."

on

http://www.aa.com/i18n/AAdvantage/re...servations.jsp

which can also be reached by navigating from www.aa.com, "AAdvantage" tab, "redeem miles" link, "Learn more about making flight award bookings."

It's always good to familiarize yourself with the airline's own website.
