I have been forced to change to Northwest for weekly Chicago - Detroit flights. United's schedule doesn't work anymore. ORD-DTW is 6:39 am (too early) or a flight after 8:00 am. DTW-ORD, there used to be an evening flight, but now the latest flight now is 5:22pm.

Oh well...I qualify for 1K via miles (as opposed to segments) and I earning appx. 250 EQM each way is useless.

Complimentary upgrades on NW for every flight have been nice..
