I noticed this last weekend as well, and I think generally there would be more O&D. Getting to NYC from BGM is not that easy of a drive, either out to Albany or down through Scranton to stay on interstates...not to say that getting to DC is an easy drive either but hey...

DL has also downgraded it's DTW-BGM routing to two daily, down from three and maybe (if memory holds) even four turns a day...
