My theory is that the increased turnaround times are due to the fact that people are too stupid to board a plane properly. And Airline staff is doing less about it than, say, 10 years ago, probably being afraid of social media shitstorms or whatever. I'm a frequent flyer, and the sheer carelessness of how people waste the time of everyone behind them in the boarding queue still surprises me. As if in the moment they reach their aisle they immediately forget they, too, were waiting... I do not remember things to be so bad 20 years ago, and even 10 years ago. Some airline staff was quite active in herding the cattle back then, but also the cattle maybe was not as ignorant as today. But maybe I am just becoming an old, grumpy man, and nothing has really changed. Who knows.
