Cargo doesn't care about the inconvenience of stopping for gas, and that allows cargo airlines to load the planes heavier (remember that much of a passenger aircraft is filled with air, not cargo). Anchorage is also within a 9-10 hour flight of almost the entire developed world, and massively overbuilt from the days when trans-Pacific aircraft had to stop there due to range limitations.
