Unfortunately what you've experienced are largely the result of an airline that has been run [for the last 10 years] with one goal and one goal only.
To leverage the very most that management could in the way of performance bonuses for themselves.
It has to be said that in this regard they were spectacularly successful.
As you rightly say.
"Shame really"...........
Whether the reputation of the airline as a premium carrier is salvageable or not, I think, remains to be seen.
