The North Terminal is terrible in comparison to any major airport I've been in. The McNamara Delta terminal compares favorably. Hard to believe this was built in 2008.
It's a shame how much capacity this airport can handle yet they don't nearly meet it any more. It used to be soooo busy, now it's just falling down and all the renovations were for nothing :(
One huge weakness of the DTW is the lack of any public transportation lines connecting it to the city. No transportation whatsoever. Unacceptable by any standards other than American.
