Another vote here for "I'll believe it when I see it".
Only 10 years in QF and I lost count a long time ago of how many of these destination rumours I've heard. It still amazes me how excited we get about them, until the rumour just fizzles out eventually.
As a rule, QF mainline doesn't open new destinations. It only closes off old ones or siphons them off to code-share or cheap offshoot airlines. Marketing gurus that our crowd are.
