What has gone through for me this summer is two postings (that I put up) for I get 15k Alaska Airlines for 10K Continental.

I'm one of the posters of those random crap trades - none of the really bad offers have gone through but I leave it up just incase someone sees my offer as worthwhile. I feel I never know when someone will have some miles they feel are worthless and want to trade them away. For example if I still had my 1,500 US Airways miles I'd probably happily trade them for 500 AK miles (3:1 ratio).


Edit - also the fees to trade still seem rather high, so I feel the out of pocket cost to me is more bearable when the trade is uneven. And a final note - the trades are not quick so make sure you plan way ahead, this is not good for last minute top-ups...
