I have two fleet maintenance tracking placards in my car; get an oil change, record the car's total time, date, mileage, and work done. 'Course it makes answering mechanic's questions easy:
Mechanic (trying to run up the bill): "When was the last time you did xxxxx."
You (reading placard): "XXXX, not due 'til xxxx."

Back to the thread, you might be a regional airline pilot: When the airline claims there is a flight up at all times of the clock, and yes, there is a time when there is only one flight up out of 274 airplanes. It's aloft at 3:30 AM, and you're flying it.

You are an uber cool regional pilot when your airline has a mainline operation and when asked who you fly for, respond with the mainline name.
