I was just browsing through the fare rules, and it looks like they've quietly slipped a couple of changes through on the 20th of August, and one in particular (the change of booking class) I think will spell the death-knell for OWE mileage runs for those in some programs. The two changes I can see right off are:

Class

ECONOMY: M* (QF/BA/AA/AO/AY/CX/IB/EI/LA/LP)
* FOR BOOKINGS MADE ON/BEFORE 31AUG03)
ECONOMY: L* (QF/BA/AA/AO/AY/CX/IB/EI/LA/LP)
* FOR BOOKINGS MADE ON/AFTER 01SEP03)

and

Payment/ticket

* TICKETING TIME LIMITS:
1.WHEN RESERVATIONS ARE MADE 61 OR MORE DAYS BEFORE DEPARTURE TICKETING MUST BE COMPLETED WITHIN 14 DAYS AFTER RESERVATIONS ARE MADE.

2.WHEN RESERVATIONS ARE MADE 60-22 DAYS BEFORE DEPARTURE TICKETING MUST BE COMPLETED WITHIN 7 DAYS AFTER RESERVATIONS ARE MADE.

3.WHEN RESERVATIONS ARE MADE 21-6 DAYS BEFORE DEPARTURE TICKETING MUST BE COMPLETED WITHIN 3 DAYS AFTER RESERVATIONS ARE MADE.

4.WHEN RESERVATIONS ARE MADE 5 DAYS OR LESS BEFORE DEPARTURE TICKETING MUST BE COMPLETED ON THE SAME DAY.

Take a look on www.travel.com.au for full fare rules - no doubt there's other sources around the net to find them as well.
