Competition. We have the same situation here, flying from upstate NY. There is a direct flight to MBJ from PHL, and it's more expensive to take that from PHL than to fly from here to PHL then get on that same flight. The reason is that from here I have the option of flying to Detroit and from there to MBJ, so it puts American in competition with Delta from here, so they match Delta's price. They may also have decided to simply charge a premium for direct flights.
