With all due respect, what the hell are you talking about? Flying has never been “a pleasure”. Back in the 70’s it was basically low altitude turbulence all the way from point A to point B, in a tube full of cigarette smoke.
Planes have only gotten more comfortable over time. Higher altitudes mean smoother and faster trips. Better cabin pressurization has made physical side effects of flying, like gastric issues, headaches, and fatigue far less of a problem. Better rules and processes have been introduced to make the flight nicer and safer. Seat size and leg space can be pretty limited, but I’ve never encountered anything completely unacceptable in my many times flying.
I think it’s obvious what the problem is: Americans. We fucking suck. Planes are the same all over the world, and yet America has the lion’s share of the nightmare passenger stories, because we have an attitude problem.
This was a 2h40m flight from Dallas to Charlotte. I don’t think you can blame the plane for this passenger’s downright animalistic attitude towards airline staff during a short flight.
