aircraft fuel our operations and financial results are significantly affected by the availability and price of jet fuel . based on our 2014 forecasted mainline and regional fuel consumption , we estimate that as of december 31 , 2013 , a $ 1 per barrel increase in the price of crude oil would increase our 2014 annual fuel expense by $ 104 million ( excluding the effect of our hedges ) , and by $ 87 million ( taking into account such hedges ) . the following table shows annual aircraft fuel consumption and costs , including taxes , for american , it's third-party regional carriers and american eagle , for 2011 through 2013 . aag's consolidated fuel requirements in 2014 are expected to increase significantly to approximately 4.4 billion gallons as a result of a full year of us airways operations . gallons consumed ( in millions ) average cost per gallon total cost ( in millions ) percent of total operating expenses .
