Why don’t plane windows match the seats?
Have you ever sat near the window but actually saw nothing through the window itself? Did it happen because it was on the same level as the back of the seat or even right behind it?
It turns out that this happens because airlines try to squeeze as many seats into one plane as possible. Aviation companies provide airlines with recommenations on how to install seat rows correctly, but no one usually follows these rules.
Tracks on the floor of the aircraft allow rows of seats to be organized at the airline’s discretion and companies use this opportunity to increase their bottom line.
