Ah, the ingenuity of American Airlines! Just when you thought there’s nothing left to innovate in the airline industry, they go and introduce ‘new’ tech to prevent people from cutting in line. It’s almost as revolutionary as inventing the wheel, but for queue management. Oh, and let’s not forget the ‘sound goes off’ feature – the future of high-tech alert systems, I’m sure. Bravo to Chicago O’Hare for embracing this cutting-edge innovation. #QueueRevolution
