This one is something that has always bugged me. When I wait for my upgrade to clear I usually wait until the last few passengers to board the plane. And when it does clear, my name sometimes doesn't appear on their list right away. There have been a couple of times that I've been asked if I was an airline employee or an auditor. I really didn't like that. What difference does that make? It almost seems that I am not worthy of being there given that other passengers paid full fare and therefore deserve a better treatment.
