If you're all so smart, why don't you go and start your own airline to compete with Cathay?
Anyone who thinks that getting the super jumbo is the key to profitability is truly clueless. While it may attract 2 or 3 more business travelers than a 777, it still has operating costs that far exceed those 2 or 3 pax. To make money on that aircraft, you have to fill it..which leads me to my point: Cathay is struggling due to a downturn in premium travelers as well as high fuel costs.
