"Will have to"? I think they can easily make a case that it will be sold only with certain ticketing classes. public carrier contracts limit to moving people and may be providing some food options if flights are longer than a certain duration. There is NO law forcing anyone to sell alcohol. If you are making an economic case, then please elaborate.

I generally feel people are little nicer on international (esp long haul) flights compared to domestic "long haul" ones, but we have seen the occasional weird stories and aircraft turnarounds with those too.

An erratic person could be a danger to all pax and it is reasonable to fear an erratic person on board.
So whether the door could be opened or not is completely irrelevant.

Honest question:
We know most of the boarding/emergency exit doors are the plug type (such that the interior of the door has more surface area than the exterior and can not be opened with a reasonable pressure differential) but what about the “power” doors like in the front of the 767 and 777?
I imagine there must be some kind of pressure interlock switch to inhibit the door opening at high altitudes, but if the cabin is pressurized to 8,000 feet, then wouldn’t the door be operational at 8,000 feet and below?
I guess the same logic would apply with the plug doors, meaning that they would be “open-able” up to 8,000 feet?
I recall news stories of times when doors were opened at high altitude airports like La Paz where the pressure was not equalized with fatal results for those outside the airplane.
But for the calculations- If a strong person can lift 400 pounds, and an emergency exit door is 2 feet wide by 4 feet tall = 8 square feet = 1152 square inches = then 400/1152 = 0.347 psi = or about 660 ft of altitude differential.
So theoretically above 8660 ft the door should not be open-able?

Flights where every single person on board owns a passport are often a bit more civilised.
