I have long felt that those airlines with Frequent Flyer schemes (unfortunately not the charters) could offer a little Saturday morning course in evacuation procedures which could then be linked into the res system and these seats allocated first to those passengers. Such is the demand for exit-row seats among members of these FF schemes that I feel they would have sufficient takers.
Flybywire raises an interesting point about the honeymooners etc champagne packages, which seems to show that on landing the pax deliberately seated at the overwing are those most likely to be inebriated. In any rational society the CAA would have dealt with this.
