In the numerous times that I've been through DTW, it looks like NW, I mean DL

, has only used 1 jetway for A330s. Can anyone confirm whether or not this is still done and what the usage is for the DL B777s?
This just seems like a waste of money building dual jetways and only using the dual feature for the B744s!
Not to mention, the WBC passengers don't get to feel snooty with their own jetway.
Any engineering point of view? I figured that with so much money into building the airport, the dual jetway system would've been designed for any wide body aircraft.
