I agree that it is troubling having someone else know all your key information, especially with the travel date so far away. I acutally had this same thing happen to me before (where they e-mailed the reservation to another e-mail address). My e-mail has my first and last name but they e-mailed it to an address with my first initial and last name - it ended up going to my dad's account as we share the same first initial! I wasn't too worried he'd be canceling my reservation
