Well here is what I found out from points.com

Transferring from (A) 1,000 miles into (B) Clickrewards:

Air Canada - doesn't participate
American West - 75
American - 62
Beenz - doesn't participate
Midwest Express - 87
Phone Hog - 500

If anyone else has usefull tidbits, or thinks about better ways to convert please speak up.

My goal is to get my miles into NorthWest WorldPerks, and this is why I am leaning toward using ClickRewards.
