No understanding of the two operations? Thats very funny! We understand the operation well, especially when we maintain our ETOPS recency in the A/C and the sim. Its just water below you as apposed to land, and a crossfeed valve that needs to be checked near the end of the flight. Wake up guys, this banter is not about understanding operations, its about economics and which operation can do the job for the cheapest price. PB will fly to the USA and beyond. Reason being, staff are cheaper and the whole operation is cheaper. End of story. PB guys, start looking at real estate prices in Sydney, and look at what your salary will get you there!
