I think you are mis-judging 'convenient to access'.

Let's use Atlanta as an example. If you go from ATL to downtown Atlanta, you'd consider it close and convenient. But if you live in a northern suburb like Marietta, you don't.

I'm guessing that 313WX is really 586WX or maybe 248WX. 734WX would find DTW quite convenient.
