How much does a gallon of aviation fuel cost the airlines?

Current prices, which have risen some 60% in the past year, range from $4.50 to $5.50 and up per gallon for Jet A. Some carriers who were able to hedge their fuel purchases (by buying future fuel at fixed costs) may be paying much less. The military also pays less for their fuel. I think today's military fuel may only cost around $3.50 per gallon.
