@berman_allen @MelpomeneMel @SuitsTracey @TySopko 2 million boardings per day in 2019. So roughly 2 per person per year. If typical flight is 2.5 hours that would be about right.
It's skewed because some never travel, some travel very often.
@2019年，berman_allen@MelpomeneMel@SuitsTracey@TySopko每天有200万次食宿。大约每人每年2个。如果典型的飞行时间是2.5小时，那就差不多了。
它是倾斜的，因为有些人从不旅行，有些人经常旅行。
