I'm pretty confidant that the average elevation of the global population is well under 1000', probably within a few hundred feet of sea level.
The average elevation of air travelers actually may be a bit higher...folks in the boondocks may have more need/desire to travel.
Being obtuse, or you really don't get it?
You do understand that this is about cabin pressurization and not where people actually live, right?
Again, for those too slow to read the first few times, you're welcome to do the math city by city and find the actual population at sea level if you wish, but it's really irrelevant to the fact that there's no economic benefit to pressurizing cabins to sea level, nor is there a particular need given that such a large percentage of the worlds population doesn't actually live at sea level.
You go ahead and spend your evening coming up with better numbers, if it's that important to you. Until then, put up or shut up...and do try to stick with the subject of the thread, will you?
