I also heard a rumour that QF is looking at going back to OOL ex SYD and MEL, and also LST ex SYD and MEL.
Also been hearing the same thing. The reason being proffered is that with DJ introducing a 'proper' J class in the short to medium term, QF will need to offer a premium product into OOL where we don't currently.
I agree that load factors have been great recently although it is the beginning of school holidays around the place so perhaps that has a bit to do with it.
