The new fatigue rules have been delayed a year too. That's good news because seemingly they are listening to industry rather than dumping the new rules on everyone. That and they probably also realise nobody in casa know the new rules either!
It's why I answered their survey and gave some very honest reviews. Worth doing. There's some good questions in there such as "how easy are the new rules to understand" and "how well do you think casa staff understand the new rules". Yes, I scored them poorly there before you ask, because it's the truth.
