I spoke to the captain that was flying the NWA cargo plane out of CVG to Anchorage the other day, and he said they could not carry jumpseaters. Only if you work for NWA. They even load the plane at a Delta gate, but they still can't do it. I also spoke with a DHL pilot, and he said they could take jumpseaters on the Airbus fleet, as it had a cockpit door. I hope this helps you.
