Just to draw attention to a teeny point in all this.
It is the easiest thing in the world to actually imbibe enough alcohol and to behave in such an obvious drunken way as to be refused embarcation onto an aeroplane.
In fact, it could be a jolly decent way of ensuring that wife and irritating parents in law were blown to smithereens, as they winged wherever, all baggage together in hold, booby trap primed and set. Forever afterwards, the surviving family member would be justified in extolling the benefits of alcohol, for truly, without its effect; he too would have boarded and been blown up.
