Our situation is not dissimilar to
drron's I think. Most of our income comes from sources that have taken a big hit. And sadly, at my age, there is very little opportunity to make up the lost ground assuming any recovery takes a while. So for us, the changes to lifestyle will be long term.
Consequently I cancelled a DONE5 and some associated travel on Friday. The DONE5 was due to start from NRT back to SYD at the end of November. Because of the fall in the Aussie Dollar, I look like I'll make a goodly profit on the transaction which was done at 97 yen to the dollar. :-| That is. when AA and CX get around to recrediting the cash. The inverse is that I'll lose 40K+ Amex MR points.
For us the DONE5 would have ended up costling about AUD70K over the course of the year with 10 or more weeks in US, South Africa and Europe. I can't justify that at the moment.
So I'll be getting my travel thrills from reading
QF009's TRs next year.

Worse things could happen!
The negative is that it will leave me around 1000 SCs short of of LTG. And I'd fully expect changes to the rules over a longer period which may make it difficult, if not impossible, to attain in the future. But if you ain't travelling, you don't need it.
My WP will last to November 2009 and longer if they take pity on me, and that may be handy for free dinners at the CNS QP rather than the salvos! If you see someone in the corner stuffing bread rolls into his bag, you'll know who it is! :mrgreen:
I do still have repositioning award flights between Australia and the US but, of course, the April one is from LAX to SYD and the July one from CNS to SFO, ie the wrong way around. There is some availability to move one to reverse the order and I'll do that (for 2500 points each) tomorrow just in case there is the opportunity for a US trip later next year.
I'm doing my best not to be too depressed this weekend. At the end of the day, it's only money.
