Qantas has recently become consistently cheapest (and by cheaper, I'm talking cheaper than Qatar et al) for my regular trips home. Not only that, the flights are nowhere near full (last flight was about 40% on an A380). Not many up front, either.
You don't have to be blind freddy to realise they can't continue like that. I'm becoming nervous about forward booking- I can't believe I'm saying that about QF int.
