Can I be the diplomat here?
This silly "we do it better than them" has got to stop! Are we still in the schoolyard?
Cx has a very good safety record and trains to a high standard.
I am not so sure that the extra work that they put you through is the reason for this safety record. AA doesn't seem to have it and they do it just as safe, with probably 10 times the sectors per month we have.
In the U.S. they take a more practical approach than their european/oz counterparts, which is just a different way of doing things, and is not less or more safe, in my opinion, just different.
Cx is an airline of diversity, so lets embrace that and learn something from eachother.
