(An interloper from the fractionals - hope you don't mind.)
As a fractional pilot, we travel on the airlines every week to and from the plane, always on tickets. TSA is a big issue for us, because of the inconsistency. Some consider us pilots, let us use the short line and take through our liquids. Others consider us passengers. That's a challenge when company policy says we can't check a bag on the way to the plane at the start of a rotation.
My favorite was DEN, where the ID checker said my badge was no good because we didn't fly there (I didn't bother arguing my plane was across the ramp, just pulled out another ID). Thirty seconds later, I was wisked into the fast lane and allowed to carry my Diet Coke through the checkpoint because I was considered a pilot.....
