At the time of the event, crude oil cost $50.91 per barrel. Since there are 42 gallons in a barrel, that means crude oil cost $1.21 per gallon. If the cost of crude were to rise to 2008 prices, in which the cost per barrel of crude rose to $139 and the dollar margin on jet fuel remained the same, what would the gross margin of that flight have been with the 2008 price of fuel for the fully booked flight?How about with only 499 passengers?
