Actually my survey was over a period of 2 years or so on about 30 flights with a variety ports. And, with airline surveys, as you probably know, the preferred method is to establish a closed loop of survey participants, over a period of time, over a range of routes and seasons and time of day, and track the responses of those people. They KNOW, that getting a random survey from a random passenger on a day when random things went wrong (or particularly well) is in no way actually an accurate representation of their "product". Did you also know that in such surveys, when people rate 0-10, they typically only look at responses in the 3-7 range, because the extremes can usually be written off as overly passionate responses? Anyway, my comments were about attitude of the airline and its in-flight service and not about an industrial dispute that hadn't yet occurred.
By your logic, when AJ grounded the Qantas fleet and stranded people all over the world its product became trash? And BA last weekend? Cancelling all those flights and stranding 1000s of people? That would still not impact my review/opinion of their product, even if I was affected, as I am able to separate the 2 issues....
