I actually really like that.
On the other hand, just did a mock booking on a flight to Canada. Seems to be able to be applied to codeshare flights now (saw the star on a flight operated by Air Canada, and it seemed to work, though I didn't actually book it) - the terms on mine, and my experience from the past, it only worked on UA/UAX operated flights. Also, discount was more than cert value - my cert is $300, though price came down more than that - by about $22 extra.
