I guess I have been lucky too.

I've been converting my stranded AmWest miles to AA (at a lousy ratio of 10 miles convert to 1). Incidentally I found that making smaller conversions yield more miles than if I converted my entire miles in one transaction. So I've been doing about 10 transactions a day, earning 2X entries into their sweepstakes, and if I am lucky I could win 100,000 AA miles.

The downside is that my AA account page does not show all the activity as they can only display a certain number of transactions (44 in my case).
