I've been asked by passengers. That's the most fun.

"Are you in first class?"
"Uh..................... yes. Yes I am."

Honestly, I never understood the pax at the front of the priority line looking to be SURE he's on the plane first because he always seems like a regular flyer. Never a newbie.

The more regular flyer I became, the less extra time I wanted to spend on the plane (certainly, at least, at the gate).
