Etops,
KLM, LH, and BA are European (obv) companies and, therefore, are tied to national pension schemes, wheras, the US companies, in addition to the hefty hourly duty pay, have a private pension system. Apples and oranges mate. No EU carrier can or would apply a COMPLETE US type system. That said, my old EU company did have duty and trip rigs in place to guarantee minimum hours paid per day or trip.
Without going into the throngs of which is better, or worse, they are simpy--different.
I agree with you that implementing a COMPLETE US system at CX is not the way to go. However, some rules to protect rostered pay and to secure min pay per day, sector or trip would be beneficial.
Cheers,
