Sure, but it would also be nice if airlines didn't put space between chairs so tight that most people do not have a comfortable amount of leg room.

What I would give to live in a world where user/customer experience was prioritised over squeezing as much profits as possible.

And no, "tallish" people will not be the only ones facing trouble standing up. I am of average height. I cannot stand up in my seat on a plane.

I guess that depends on the country. In mine the average height is only around 170cm for men and around 160cm for women so less of an issue. In countries like the Netherlands, the average height(for men) is around 185cm so for them even 'short' people will face issues.
