Only way to compare apples to apples is, what are the ASM/ASK costs and the reliability rates. This includes possible lost revenue due to maintance issues with regard to extra inspections, etc. Nothing else matters, except maybe extra profit made from cargo carried.
Of course we can make a connection to what our profit shares, pay raises, and increase productivity levels have been since the beginning of the 380 operation in 2009. Cause and effect? Whose to say, you be the judge.
