for some background:
i have a decent amount of amex points that i am/was saving up for 2 trips for 2 people; my idea was to go to Australia or somewhere around there and use a points service/adviser to get those elusive redemption rates of 5-15cent/mile.

typically for domestic points in coach -- which usually was always transferring to delta -- i was able to get around 2.2cent/mile.

now:
we're planning a vacation to mexico around thanksgiving and poking around while coach redemptions blow the first class ones are good @ 2.6c/mile, although they'll take up about 25% of my points.

what's your redemption threshold, would you take 2.6c/mile or hold out for something much much better?
