I'm only stating that the cost for a flight is over 2k. Normal operation of any jetliner is very high with Jet A fuel costing over $4-$6 per gallon. So take that X 20,000 gallons per trip. It gets up there. So for taking direct flights is not that common.
I'm still unsure whether you're arguing for or against FE. Are you saying that direct flights (Shortest FE route, across the Hub) are not common, which increases fuel costs, or simply making a general statement about how much fuel is used on transpolar flights?
If the first, what prevents an airline from cutting costs and time by using the direct route?
The 747-400s used on these flights can hold almost 50k gal of fuel, BTW.
