As a 6'1" passenger myself, I can only assume you have short femurs. I've had that exact scenario happen to me on a flight - when the person in front of me reclines, my legs from my rear end to my kneecaps do not fit in the space provided in an economy seat.

I book seats that are Economy Comfort (I fly Delta) or exit-row seating, but when flying with my wife and children I sometimes need to choose comfort or sitting near them. (For the record, I choose to sit near them when I am forced to choose.)

I'm a little unhappy about being charged an extra $100 to fly Economy Comfort just because I happen to be in the 90th percentile for height, but I understand the engineering and social issues of providing seating in a fixed space for 200+ passengers.

I believe we're both slightly over one standard deviation above the mean for adult male height.

Regardless, I am a competitive distance runner (and have the right body type for the sport). My femurs are likely even larger than yours, and yes, my knees stick a little bit outside of my space into the adjacent seat, but I am still perfectly capable of sitting in my seat. I've had overweight seatmates that encroach more on others' personal space than my knees do.

Re: overweight passengers, if I ran an airline, there would be a seat with side panels to test your fit. The seat would have side pressure sensors. If you can sit in the boxed seat without touching either side, fine. If you can't do so without touching one side or the other, you'd have to pay more. We'd also charge for weight, something per-pound. It costs more in fuel to move each additional pound.

There would be a required training course for boarding and unboarding which all potential passengers would be required to pass. We'd also teach people how to put their carry-on in the bin in the correct orientation (with the widest side inserted depth-wise and the second widest dimension vertically such that 4 bags can fit into a normal bin instead of 3 or 2 + that one person's purse which should be under the seat). It'd be like a marching band, with timed choreography. We'd board using the front and rear doors. I bet I could reduce average boarding time to 20% of what it is today.

There would be no in-flight screens for entertainment, no drink or snack service, etc. There would be a double-walled [possibly plexiglass if no lighter alternatives exist] section for people traveling with children under about 12, with a bit of space reserved for anyone acting like they're under 12. This would contain the noise and smells. If this could not be made to work, simply restrict booking to passengers older than 12, then everyone else can appreciate baby-free flights.

The benefits of all of this would be reflected in ticket pricing and clearly-stated business practices + expectations. It would have limited appeal, but excellent customer service and I would expect a cult following of loyal frequent travelers who appreciate efficient travel.

Of course you would get the obvious comparison to the sizing box they use to determine if a carry on bag is allowed onboard.

I would guess you would need a fairly big legal defense fund for this endeavor.

It's a thing...some people can't fit.

Average seat pitch is 31 inches these days, but the room you would have from buttocks to your knee would be smaller than that. 22 inches isn't uncommon: http://si.wsj.net/public/resources/images/PJ-BY155A_MIDSE_16...

"Buttock to Knee length" seems to range from about 21 to 25 inches: http://ergotmc.gtri.gatech.edu/dgt/images/hbfg0713.gif

It's not hard to imagine someone with 24 inch+ b-to-k having trouble fitting them into a 22 inch space.

My son is 6'3", and has real issues with this.
