I still think of "FedEx Ground" as an acquisition/rebrand and I would not be surprised to learn that the integration between Ground and Actual FedEx is still minimal.
This is (or was the last time I was more directly involved) still how it was; FedEx Ground, Freight, and Express were basically three separate companies, with different portals, phones, and service levels.
UPS was much more integrated, though Freight is still a bit disconnected.
