Wow! Thanks for the fast replies (and the link to the other thread). Much appreciated. This info appears to be yet further validation of my decision to move a good chunk of my domestic flying away from CO/UA and towards DL... as a top-tier on CO, my LGA-CLE flight (400 miles) yesterday didn't clear until 24 hrs in advance, whereas as lower-mid-tier on DL, I cleared a Friday evening ATL-DEN (1200 miles... 3x as long) over 4 days in advance. I have no complaints about my UG% as a 1K, but I've gotten REALLY frustrated with the lack of WiFi, and the total crap-shoot that is in-seat power availability on UA [no way to know until you're on the plane if your 757 or 320 a) has EmPower, or b) if it's working]. This sure has been encouraging so far... I know, I know, don't get my hopes up
