That leaves Boeing to get us MIA-DTW, and not a 727 of any type. I'm going to go out on a limb and say it's another one-stopper on a Piedmont 737-200 via CLT.
There's only one one-stopper involved here, and that was the NW D10. However, it didn't get picked up out of DTW.
Piedmont was not involved, nor was the 707 or 737. Boeing did however play a role...
Hmm... lots of new info. Here to guide you on your way to the correct itinerary...
Good luck! I think you'll solve this very soon...
