DEN earlier this week the GA announced that she would be boarding EVERYONE according to their BG#, so “all of you standing over there” (points to the pre-boarders) need to get in the BG1 line. She said when she called preboarding, she needed the other folks in BG1 line to move over to let the people through. About half the pre-boarders went and got in the line, the rest of us just boarded like normal. She then proceeded to call extra time, military, GS and 1K all at the same time. 757-300.
