Just to add fuel to this thread's fire, another "metric" for a premium airline could be its success, economically (ie for shareholders).
At not just the "end of the day" but also the start, it is a company, a business, not a charity. The QF share price has rocketed over the past few years. IE it has changed and has become a succesful business. They may be selling Corollas at SV6 Commodore prices, BUT THE PUBLIC KEEPS BUYING THEM!! Succesful marketing, succesful hype, whatever. Many on here shout about how you can get a better car for less elsewhere - maybe true, but why would Qantas change from what is working for them??
