Also how can this possibly be true for every human being? I'm only 6'5'' and for any plane I've been on this has not been true. Including "newer" planes eg. the 787 Dreamliner.

Never seen this, was on a Qatar 787 recently, and an a320neo, and freshly densified 777, where is this magical seat you speak of?

  Not sure what you're asking, did you misread my original comment? This magical seat does not exist, even on new planes.

6’5” is something like 4 SDs above the mean for adults (male & female), FWIW.

  So what is it worth? What help is this to someone 6'5"? He can hardly change his height to be more in line with the average person.

    It might help them to better understand the tradeoffs airlines make when designing their cabins. There are always exit row seats, which not only have longer seat pitch but also have rows ahead which cannot recline. Maybe airlines could waive the modest upgrade fee for passengers of extreme height.

  I didn't realize that. I say "only" because my father is 6'10'' and many of my siblings are taller than me. My perspective is skewed.

  Using averages to accommodate passengers doesn't work. If you do that, 50% of your customers are going to be very unhappy FWIW

    Accommodating everyone except those taller than four standard deviations above mean would (assuming gaussian distribution) mean accommodating 99.997% of your passengers.

      This completely misses the point. First of all, you are only correct if assuming a gaussian distribution of heights (for which I have seen no evidence). Who cares if it accommodates 3SD, 4SD or 5SD? You would never engineer a system around standard deviations of a distribution of heights. Instead it's about marginal cost. Ideally you would accommodate 100% of your passengers unless their marginal cost is just too high. You are also assuming the distribution of passengers is the same as the distribution of the population. Or the distribution of customers willing to pay certain prices is the same as the general population. Airline seating is very complex as it's not a fixed price, changes constantly, and even varies from seat to seat in a single flight. Prices aren't fixed so just because you increase marginal cost does not mean reduce profit. Lastly it also ignores completely the fact that even a shorter person would enjoy the increased room.

        You responded to a comment about how a case is extremely uncommon, with a suggestion about half the population. All I pointed out is that your argument is less than perfectly applicable to the comment to which you're responding, by stating a mathematical fact. I didn't assume anything, ignore anything, assert anything, or even draw a conclusion about what should be done. Just spreading facts. Call me Johnny Factseed.

  One of the few times I feel underrepresented in my life is that moment when I am shoving my knees into the seat in front of me as I slowly wedge my hips into my assigned seat. I wonder if you could start an airliner targeted at tall people and only have seats that can fit 7 ft tall human beings. We really do need a lobby.
