Anyone who’s ever travelled by plane knows that the process of boarding is almost invariably nightmarishly slow, and anyone who’s looked into the reasons for why know there are better methods than the one most airlines use. But what is the best method, and why doesn’t anyone use that?
The answer is simple: it’s basically impossible, as YouTube CPG Grey illustrates in a video that runs through the basics. To minimize the time that boarders stand around uselessly waiting, the trick is to position everyone just so in order that as many of them can be placing their bags in the overhead bins simultaneously. The catch is that to do so requires everyone to line up in exact order. That’s right: one-person boarding groups.
This method is clearly unrealistic for anything less than preprogrammed automatons, but a simplified version that sees travellers boarding by alternating rows on alternating sides would also be a massive improvement over more prevalent methods. Maybe, if we’re lucky, an airline will actually try it. Then again, maybe they’re just too busy figuring out ways to stack us on top of one another.
