Qantas went on sale for their new Asian timetable overnight, and the deals are actually worth letting you know about in case you’re interested.
If you can score a sale fare for dates you want, $700 return in Economy to Singapore, or $3800 return Business Class to Hong Kong is about as good as a full service carrier will probably get on these routes.
Here’s a quick screenshot of the deals departing Sydney:

You may find Cathay Pacific, Singapore Airlines and such responding with sales in kind – let’s hope.
Normally I don’t write about general sales and such as I figure these will most likely make their way to you one way or another – if you’re interested in a specific destination / date you are probably checking in on fares regularly enough, and I imagine a large percentage of population gets them through email.
Does anyone know if Qantas have a regular schedule of “sales” for fare promotions? Is there a “new year or summer sale” in their schedule?
It’s hard to predict reliably, especially for International travel. The most reliable sale is the Early Bird for the following calendar year which usually crops up in November/December. Unless you’re travelling at peak times, usually a sale will come up for the dates you want eventually, just sign up to the sale emails and keep an eye out. Depends how firm you need your travel plans to be!
Funny you should say they probably won’t get much lower, a news story on Bloomberg today is reporting they have increased their capacity on Asian routes by 40% due to the Emirates alliance and are cutting fares to $360 one way to Bangkok, Hong Kong and Singapore.
