Well, I went and bought 3 of ´em (since there are three of us who want to travel to OZ to meet our recently-rediscovered relatives in MEL).
Some (actually quite a few) questions:

1. To change the ticket, does one go directly through Qantas? Is there a ticket reissue fee even if it is a fully changable ticket? Also, under "refund procedures", it just stated "normal refund procedures apply" - does this translate into fully refundable?

2. For purposes of refunds, is the amount pegged in USD or the Estonian currency?

3. It has been mentioned by some that QF can later impose "high season surcharges" - can they really do it if in the fare rules it states that there are no season rules?

4. I seem to recall reading that if you stop over at an intermediate point, even if stopovers are allowed, the fare will shoot up if flights to the stopover point are more expensive. Does this make stopovers on the way impossible since any point on the way would be more expensive? How about a stopover in OZ at one of the other cities bookable with this fare (if such a stopover in OZ would work, would it no longer be possible to add it once the price goes back up?).

5. I was only able to force this fare with Best Fare Finder on travelocity. Has anyone been able to use a booking tool with more options (e.g. stopovers) to force this fare?

6. Looking at the fare rules, I would not have known that travel on another carrier to LON is permitted (or have I missed something) - for future reference, what´s the key word(s) to look for in such cases?

7. Re: the claim that they may not need to honor the fare if this was found to be a mistake - does this apply if the ticket was bought in the U.S. (well I bought it on .com, with my US-based credit card and shipped it to the billing address)?

8. For a Y fare, why was there no availability on certain days?

9. I could not find the MPM in the Travelocity rules - anyone care to let me know?

10. What´s the validity period of the ticket? Is it a year from purchase? A year from date of o/b? If the latter, does that mean it can not be changed to a date earlier than the original o/b?

Thanks for any and all help!
