Thanks for that, Mark. What I meant is that you just can't buy a genuine Y OWE or GE fare, at least through Qantas: your choices are discount economy, or genuine business, or genuine first, so far as s/credits go.

However the OWE and GE Biz and First fares represent quite a respectable discount on the costs per leg, yet you reap the same benefit as those who have paid considerably more.

What started the enquiry process is that the QF website's info page re OW RTW fares makes no mention that the economy fares listed are in fact discount economy.

The end result is that the front-end fares are really good value, while DVT-class is only so-so.
