I have 6 bases within the USA, each with cargo destined for RJAA in Japan. I use the 757 cargo, and for range limitation reasons, all the planes refuel at PANC, and then onwards to RJAA. Could my airline not have the option of establishing a cargo hub at PANC. I could then fly the 757 to PANC as before, unload the cargo at the PANC hub, and reload the cargo onto a 747 for the second leg which would be more efficient and interesting. I did do a search of the forum for this topic, and no results were returned, but I suspect this has been suggested previously.
