I used to be almost 100% CO, but recently probably am 60% NW (flights to MSP) and 40% CO. I have yet to not get a NW upgrade at the 5-7 (yes, 7) day window, but am sitting with a flights on Fri and Mon from BWI-CLE-PHX-CLE-BWI. The CLE-PHX legs (which are still booking uber cheap I-class in economy) are showing 7 seats open on the outbound and 9+ on the return. Yet, no EUA as on Tues morning? Looks like a gate-fest for CLE will ensue.
Sigh....
