Looking at a Boeing 777-200LR the fuel consumption is:
Fuel consumption in 800 miles is about 24,000lb of fuel
Well that's probably what the chemicals that they are dispersing are
supposed to achieve ;-)

Mark,
Your conclusion below is inaccurate.
It compares a fully loaded vehicle (airliner) and the extrapolated fuel
economy per passenger to the fuel economy of a car with but one passenger.
Apples to apples, both vehicles need to be fully loaded when compared.
A fully loaded, 301 seat, Boeing
I think it's actually more accurate to compare each vehical in it's
most commonly filled state. At least the airplane usually has more
than one person in it... whereas most the cars I see here have one
person in them most of the time. All the people who I see driving to
work each morning, alone,

Perhaps, to achieve real world passenger mile fuel economy averages,
presuming an average occupancy rate per vehicle could be achieved. No doubt
someone has done that somewhere. At least you can
Okay, in this case I take your point that with average occupancy rate
the jetta is more efficient. But it is also roughtly twice the mpg as
the average car in the US. So, I still think that 30 PMPG is more
realistic an average for car travel about the same as the
efficient airplane.

Not yet Zeke.
If the airline wants to tout it's highest fuel economy vehicle, so can
the ground transportation sector.
Using you're method you'd be giving an unfair leg up to the airline by
accepting their high fuel efficiency model but handicapping ground
transport by introducing an average
Looking at a Boeing 777-200LR the fuel consumption is:
Fuel consumption in 800 miles is about 24,000lb of fuel
300Lb/Fuel/Seat/3000 Miles. (Boeing spec)
That is 10 miles/pound/seat of fuel
Or 68 mile/gallon/seat.
Compare that to your average car you don't even get close.
About 5% of
So, what is the fuel economy of the average airplanes, instead of the
efficient ones? I have no idea how different airplanes compare.
Speaking of emissions, what about using biodiesel in airplane engines.
I know that quite a few people are excited about the new compression
ignition airplane
