My college age daughter is Platinum this year through my MM companion status. Generally she travels with my wife (Platinum) and me so she knows Boarding etiquette. Recently she has made several trips without us and has found that the people in Boarding Group 1 automatically assume that she is in the wrong line (BG1) and that she should get the heck out of the way. Foolish, prejudiced individuals tried to push her and two of her college friends aside physically from the BG1 line in SFO as they were connecting to EWR after a break in Oahu. As an athlete she was able to hold her ground and show them her status, but it was a bit of unfriendliness that was not necessary.
