I'm pretty sure I've seen on the GIDS before a message that says "Boarding Zone SKY" or whatever zone they are currently on. If I remember correctly, it's usually a big green box with the writing in it. Problem is, the TVs they use for the GIDS aren't always in a convenient spot to where you actually board.
