I figure it's 0.25 pounds of fuel to carry 1 extra pound for the full 3300 nautical miles on a 777. Divide that by 6.7 (not 5) to get 0.037 gallons. At $3 per gallon, it would cost 11 cents per pound. So, if you want to penalize a passenger for being 10 pounds overweight, that's about a dollar.

Since the 777 isn't designed for 1000 mile flights, you'd have to lookup the graph for a more reasonable plane like the 737.

correction: Actually, it's OK to use the 777 for a 1000 statue mile flight. The problem is that it's hard read the graph that Boeing provides on their web site for that distance. It looks like a couple thousand pounds of extra fuel for the last 20,000 pounds of payload. Even though the 777 is less efficient at the shorter distance, the cost of the extra fuel required is still less than it would be on the longer flight, or less than a dollar for being 10 pounds overweight.
