>You're asking for airliners to cater to what, less than 5% of the population?

Yes I do expect them to care about tens of millions of passengers being able to fit.

Correction, at 6'4" you're in the 98.9th percentile for the U.S. What you're asking for is simply not reasonable or fair to the overwhelming majority.

They do care. They've shown that it is more economical for private companies to not make special allocations for one subset of the population, especially when customers are free to upgrade. This isn't about airlines being evil, its about your entitlement.

Exceptional where? Netherlands would probably disagree with you.

Exception on planet Earth, obviously.

In the Netherlands a 6'4" male is in the 94.6 percentile.

US: Tall: 98.9 Percentile

Netherlands: Kinda Tall: 94.6 Percentile

Kinda Tall is probably not something you'd call necessarily rare.

And if you check 6' 2'' (which is my height),

US: Kinda Tall: 94.6 Percentile

Netherlands: Above Average: 82.2 Percentile

So i think my point stands :)
