Is it not correct to say that every and each flight is different irrespective of the airline. The irony as an ex Customer and Cabin Crew customer service training manager vast sums of monies are spent annually to this end. Still there is little or no consistency of the service or the product and unsurprisingly customer services on a flight are still the major source of complaints, after the toilets and dirty cabins.
As previously stated keep dumping down on standards and ultimately the customer seems to get less and probably expect little. Oh for the days when you could disembark after a business / club long haul flight feeling bloated and if in First light up a cigar.
