Flew out on a UK airline on Sunday. Three of the pax in the two exit rows in front of me had headphones in while the cabin crew gave the special briefing for people in the overwing exit rows and paid no attention. Cursory attention from the rest.
Flew back with same airline today and the pax next to me found a small package left from the previous flight in the seat pocket. Proved to be harmless, but not identified in the pre-flight security check.
From the comments of some posters in this thread, there seems to be a suggestion that these deficiencies are down to the regulators, but to me it seems that they are down to the airline with whom liability rests. In both cases had I survived an incident/accident, I would hold the airline responsible for failing to exercise a duty of care. Airline managements have to put in place proper measures to ensure that safety and security procedures are being complied with.
