I seek some erudite advice from you learned folk on this board. I'm sitting on 300k points in this program. I've heard rumors that changes may be afoot, which may make them even more worthless.

Should I
1. splurge on full award tkts ASAP
2. use them to upgrade on a couple of AUS to Europe/Asia flights that are coming up (bearing in mind QF upgrades are never confirmed unlike with, say, UA) or,
3. do you think there is no hurry and I can save them for when I really need them?

Thanks.
