About a month ago I took a vacation in Alaska. On the last day another guy from my tour group and I both had late flights out of ANC, so we were hanging out in the airport restaurant, watching planes and killing time before out flights. I was telling him about how ANC was a major refueling stop for cargo flights to Asia, and he asked an interesting question that I couldn't answer. He noted that pretty much everything is more expensive in Alaska than in the Lower 48 due to it's isolation, including gasoline. So wouldn't jet fuel be a lot more expensive at ANC, too?
Obviously refueling at ANC must be the best option, because so many airlines do it. My fellow traveler was suggesting that refueling somewhere like YVR or SEA might be cheaper. Is jet A in fact more expensive at ANC, but not enough so to make it worth flying farther for cheaper fuel? Or is even YVR-Asia too far for a fully loaded 742 or MD-11 freighter, and ANC is the only option? Or is jet fuel sort of the exception to the rule and not really all that much more costly at ANC?
