It's all well and good to claim that there were various external factors that weighed into the Emirates situation that led them to break curfew but surely those same factors affected all other operators on the day.
According to the article no other operator had been fined since Jetstar in 2007. So for 5 years these sort of issues would have affected every other operator at SYD but they managed to obey the rules but Emirates HAD to break them 3 times in 14 months.
Seems more like a tactical decision by EK rather than they were left with no other option.
