I find many elite-level flyers to be rude and self-important. For example, they routinely cut lines, including lines of other elites. I've been standing in an elite/FC security line at the airport and had multiple people cut in front of me. When waiting in line at the gate to preboard (as a FC passenger), other elite/FC pax always cut in front of me.

I often find elite pax to be worse than the non-elite "gate lice" that many Flyertalkers complain about.
