A closer look at flight costs

Youtube user Wendoverproductions covers costs associated with plane tickets in good detail although there's a lot of vocal uptalk in the presentation.

Looking at things from the passenger side, I think the earlier case I made suggesting that shipping from China is mostly subsidized might be wrong. If airlines are profitable with $80 ticket prices hauling around 150lb people across the country and fuel costs are a small fraction of actual expenses, then sub $1/lb shipping rates for freight seem reasonable.
