Sorry but I do not see how a flight delay caused by a safety issue can be viewed as incompetence on behalf of the airline. Incompetence would be putting people on aircraft not fit to fly. I also fail to see how this should be interpreted as $$$ payouts for passengers. We are all inconvenienced by life at some stage, but I don't immediately assume it means a compensation payout for me.
Increasingly I find this particular attitude to be pervasive and somewhat ridiculous. Just when did life become all about compensation?
