Spot on-look after the crews and the pax are taken care of too.
A pilot friend of mine now retired said no one shares the results of a screw up with the 'victims' more than a flight crew.
His corollary to that was 'we are interested in our own safety, if we get there and walk down the steps at the end of the trip so do you' See how long ago that was, pre jettys but the point remains the same and if the crew are well rested and a proper assessment of human factors comes into rostering and trip assignment the pax will be just fine.
As for this thread well , tired, demotivated crew (they were both about to leave) flying to a bad weather, tricky (captains only landing ) two hours holding (how often does that happen ) and the prospect of a long back of the clock slog back to Dubai. It might all be legal and often doable but it doesn't really sound ideal does it
