Airlines, how hard is it to onboard off-boarding protocols?

Flights can be easy; it's an easy fix, stay up all night, knockout at takeoff and magically wake up with a measly, never-ending, painful hour until landing. But, we know "easy" rarely follows flight. Flying and all of its accompanying tasks is the ultimate patience game. This is not something that is merely understood, conceptually; it is very well known and felt, not just by those flying, but now, we have a whole sub-genre of flying freakout "content".
