Anyone bothered enough to take the time to be part of a website called "notgoodenough.org" obviously has too much time on their hands.
Suffice to say, these complaints by in large (not all I might add) are driven by people who cannot follow the terms and conditions of travel they agreed to. Those 'idiotic check in procedures' are agreed to when passengers purchase a ticket (they must tick the terms and conditions to say they read them).
Yet, when the passengers cannot organise themselves enough to have check in baggage under 20kg, or be there before -30 to departure, it becomes everyone elses fault except theirs.
At Ansett, the airline bent over backwards to accommodate the faults of others. Jetstar doesn't, and yet IN SPITE of these complaints, goes from strength to strength. AVV had their 1 millionth passenger yesterday, didn't they?
I would hazard a guess that the same people who whinge the most about JQ keep on flying them because of the fares. DJ flies on much the same routes JQ does (except AVV)...enough fortitude to complain, but evidently not enough to fork out the extra dollars to fly on the rat perhaps?
