If we want solutions we need to look at what happens to the pax long before they get to the aircraft. Start with an early wake up, stressed on the journey to the airport (M25, anyone?), remote parking, long cheque-in queues, queue for immigration, queue for security, clock's ticking...the security process itself (nuff said, if they weren't wound up before they are now), get bombarded though duty free (LGW and STN force you to and it's a horrible environment), not enough seating, confusing signage (I'm frequently asked to help lost and confused pax) and that's when its going smoothy! No wonder they want a drink. So they arrive at the aircraft stressed and tipsy, add to that 1 in 4 people are afraid of flying and it's not surprising it's an explosive mix. In my opinion, the airports and airlines need to be address their considerable contribution to passenger well-being before we can make headway in tackling this problem.
