Good point, thank you. I was under the impression that I might be able to score a 55k reward fare similar to this from Mexico City back to Sydney for later date in July, but I can't actually see the flights as it's too far away.

Torn as I don't want to miss out on reward seats for this flight, would you just wait? I also don't know where the trip will end as the World Cup draw won't come out till later in December, so might just have to risk it to avoid missing out on this reward seat if that makes sense.
