> CAN-LAX is 6,284 nm.

Just add a refueling stop at ANC, the same as most cargo flights today (and the same as most passenger flights in the past).

According to a Great Circle mapper, CAN-ANC-LAX is only about 250 km longer than CAN-LAX.

Descending and climbing again will take a lot of fuel, jets are only efficient at high altitude. Plus of course the extra takeoff and landing adding cycles to the airframe.

Sure, but if it's the difference between "can" and "can't"...

It's a small enough issue that it's the routine route for cargo flights between China and the U.S. West Coast.

Anchorage is the second-largest cargo airport in the United States (after FedEx's home base in Memphis).

Part of that is because cargo usually runs on old and inefficient planes, so they really benefit from “intermediate stop operations”. Carrying all that extra fuel for a direct long-haul adds 10-15% in fuel costs.
