Some surprises:
1. US Airways at bottom: I have been able to get some good awards from them. Some examples include:
A. 2 offpeak Biz tickets LAX-MAD on US metal @60K each.
B. 2 LAX-DTW-LGB open jaws @25K each.
In earlier years, I was able to get 2 Biz LAX-Australia/NZ open jaw w/stopover on QF when US was their partner. Got first choice of dates.
2. AA below UA.
A. Last year, I put on hold 1 Biz seat @125K on Quantas using AA miles. Nothing available on UA or partners in Biz. Starnet blocking in full effect.

B. Got 2 Biz seats on LH but only 1 set of dates within a 60 day window. Lots of availability on ANA site for LH (lots of dates--some dates had 4+ Biz seats available). Decided to burn UA miles before devaluation of 2009. No problem getting 2 Biz seats on AA for my choice of dates.
3. DL doesn't surprise me. Difficult to get awards. Only have 97K on DL. May go with AS itineraries with DL miles. Found 2 FC seats during summer 2010 on AS going from LAX-ANC. (didn't go but nice to know for future reference).
4. CO: Found a trip for this summer but 3 segments each way and the return are all RJ's.

Oh well, I only have 4K left on CO. Plan to get 1K more in account and move to Amtrak.
