I meant PHL has failed as a *primary* hub, in the sense that JFK is still the main TATL hub and the planned winding of down of JFK to just a handful of TATLs to LHR and a few other cities never happend. A good example of this is pulling the PHL-MAD flight but still keeping the JFK-MAD flight even though there’s two IB flights as well ex-JFK. As for why, I think it’s simply down to PHL not having enough O and D traffic, and I’m guessing the same will happen with PHX vs. LAX.
