Passengers would line up military style. I would organize by height, weight, and for fun, clothing colors of the rainbow.
If someone tried to skip the line and board before their row was called, they would suddenly become an example to the entire line.
I would hold up their ticket, pretending to be innocently curious, and loudly exclaim, "EXCUSE ME? DID YOU KNOW THERE IS A LINE? OH YOU ADORABLE THING. THE LINE ACTUALLY STARTS BACK THERE." They would slink away, avoiding eye contact. There would be no more line cutters.
I would go beyond my job duties.
As any traveler knows, the real transgressions begin when people actually get on the plane. People stop in the middle of the aisle, spending 80-90 seconds inexplicably pawing through their bags and blocking the TWO HUNDRED PEOPLE behind them.
In my world, this problem would not exist.
I would walk through the plane with a goddamned toilet plunger through the aisle. Clear the aisles, people. What seems disconcerting would ultimately be welcomed and applauded as the plane boarded 25 minutes early.
JetBlue would wonder why their turnaround time has plummeted by 40% at this one particular gate at JFK. They would spend half a million dollars on a research study, which would lead them back to one gate agent.
Gate Agent Sethi.
Damn, that's how you do it.
