Eventually did find some 20K/30K deals (I have a total of 50K miles). The problem is that it looks like US Air is charging 50K *per person* for a coach award seat. So much for 25K equaling a free domestic ticket.

Really hate their award booking online. I entered 2 passengers and I'd been presuming the mile costs were, as I'd asked for, 2 people. Nope. Not even at the time I tried to continue after picking flights did it give the actual total--it just presented me with an ugly screen saying I didn't have enough miles.

Not very user-friendly. But live and learn--my mistake.
