I would have thought one-way tickets would be classified as flex - apparently not.

Example:
One way MEL-DXB-CDG on 11/2 for 1677 AUD is a saver.
A return MEL-DXB-CDG-DXB-MEL departing 11/2 and returning a week later is 1839 AUD and is also a saver.

Now taking all my business to QF given they have a codeshare with EY now for destinations in the Middle East. I was happy to wait when I heard the changes and see what they really meant, this is an absolute joke and EK have lost me for good.
