Quite the reverse, never found an airline where the service of one stood out from another, except Singapore perhaps, those CC served drinks as though they received a bonus on consumption. Once deplaned from a QF in LAX and presented by CC with a bag containing two bottles of wine, deplaned United at Tulla with three bottles of French wine presented by CC with white napkins still around the necks, bit of a bother being over the allowance at customs, chap went off conferred with boss and all was OK, being day before Xmas may have helped.
Never had reason to be dissatisfied with any flight undertaken anywhere in the world, other than being told to pull the blind down, I prefer to watch the world go by. A frequent Jetstar pax and absolutely no complaints,
