That's interesting. My assumption was that they were using individual examples to show the aggregate effect of large numbers of people making such choices, at a scale great enough to influence flight planning, but in a way that seems relevant to us as individuals. After all, there are hundreds of millions of people in Europe. If 1% of them make a small but material change in their travel habits that's millions of people taking fewer flights, which clearly could have a material effect on flight schedules. It would never have occurred to me that, in fact, they literally meant us to think that one person making that choice would individually have that effect.
