I thought that United's annoucement was tacky...but that is over the top. For those of you who dont know, United's announcment (which seems nice and well worded after the AA announcement) is this: "Ladies and Gentlemen, there are 2 cabins of service on this flight. Due to United Airlines security policies, we would like to ask that you use the lavitories in your own ticketed cabin. Flight Attendants are always avalible should you need assistance in locating a lavitory."
