BA give cabin crew TEN minutes from boarding a/c to complete all safety checks and searches and to prepare drinks / papers etc. and check catering. Crew are not required to clean cabin. If cleaning is deemed unacceptable , crew may call cleaners back to a/c . This then delays boarding and could impact on take-off slot which may be lost. This would then delay the flight. In an ideal world cleaning standards would be extremely high on every flight. the reality is , that if not the case , this is probably due to operational reasons. If flight arrives late , there is huge pressure put on ground and flight/ cabin crew to turn the aircraft around and have it ready for it's scheduled departure. You will probably find that this is the reason behind sub standard cleaning on your particular flight. Very unfortunate for you and for BA as you have chosen to broadcast this inconvenience and not to fly BA again. Out of curiosity , what would have been more disagreebale to you ? A delayed flight or an unclean aircraft ?
Sorry Gardener , have repeated much of what you have already pointed out.
