I know this sounds convoluted, but I was looking at "the board" at EWR and saw a direct NW flight from EWR to MKE. I thought this was a bit strange.

It was flight 4600 and leaving from gate 40. So when I was on the monorail I looked for gate 40 and it was Midwest Express. So, it makes sense that the EWR/MKE segment of Midwest Express is a NW code-share.

I think I know the answer (Yes), but would CO allow for OP credit on a NW/Midwest Express operated code-share? Since CO only operates those dreadful ERJs to MKE I've opted for ORD and a rental car.

I was also trying to figure out if that opened up any other opportunities for somewhat "hidden" OP credit flights.

From what I hear, Midwest Express is a really nice airline in coach... leather seats, 2/2 configuration, good meals, etc...
