Then why Cathay Pacific refused to introduce B777-200ER and then serve routes like Hong Kong - Toronto / New York? Because Cathay Pacific knows passengers want reliable service, and B777 is unable to perform this, and passengers have to land at extremely cold airports in Arctic when one engine of B777 is failed.

So it is totally a suicide action for China Airlines of poor maintenance to introduce B777, as there would be lots of flight diversion for China Airlines B777 over the Arctic, thus killing many passengers because of extreme cold and lack of faclilities for passengers like medical systems, clothing for sub-zero temperatures.

If China Airlines really introduce B777, then it would go bankrupt within 2 years after the introduction and purchased by other airlines for just TWD$1 (US$0.03), because of very unreliable service and lots of passenger death!!
