The fine is one of a kind in the entire aviation history.
PIA left its passengers stranded inside the plane for more than four hours in Washington, according to a foreign news agency.
US federal laws prohibit any international airline to keep its passengers inside the plane on a grounded flight for more than four hours without allowing the passengers to return to the terminal.
Any International Airline that violates this law can be fined up to $27,500 (nearly Rs2.65 million) a passenger.
The flight remained on ground for around five hours because PIA crew didn’t want to offload passengers via outdoor staircase in a stormy weather.
