so i went on a 12 row plane recently and was curious how much gas they were wasting for the 20 people that were on the plane. so does anyone know how much gas a small plane uses or how much a big plane uses or both?

You said you were in a 12-row plane, but that's not really enough info to narrow it down to a specific type. Was it a turboprop or a jet? How many seats across each row?
Assuming it was a 50-seat regional jet like the Bombardier CRJ-200 (which has 12-1/2 rows, actually), here are some rough numbers (from *deep* in my memory...):
At takeoff the engines are comsuming about 7,000 lbs/hr, for the pair. Jet-A weighs 6.7 lbs/gal, so that's 1,045 gal/hr or a little less than 17.5 gal/min.
Very shortly after takeoff the pilot reduces power to a climb setting and the fuel flow drops. It will continue to drop as the plane climbs and the air becomes less dense.
At cruise power settings at say 31,000 ft, the engines will burn about 3,000 lbs/hr (448 gal/hr, 7.5 gal/min).
If my memory serves correctly the CRJ-200 can carry something like 14,500 lbs of fuel, for a range of more than 3 hours with reserves.

A lot of good answers here. A typical transcontinental non-stop flight burns about 20 to 30 gallons of fuel per passenger (rough estimate) depending on the size of the aircraft. That assumes a full complement of 150 to 350 passengers (IE Aircraft from the size of 737/A319/20 to B767/A340) and many other variables. A lot more efficient both time and energy wise than cluttering up highways with half that many cars burning 100 + gallons each to drive across the country.

John was right about fuel burn, T/O and cruse.You asked about how much was wasted on 20 persons on board. that might be the magic number of passengers 20 for the airline to make a profit.....and then you leave the gate.

There are several electric operated airplanes, but they couldn't go very far. The extension cords were too short. No, I don't agree with you. It's called supply and demand. Most commercial flights use jet fuel, not gasoline.

The typical fuel burn is messured in pounds. Let say LA to Houston might carry about 38.000 lbs. A 737 burns about 9,000 lbs of fuel an hour so in three hours its fuel burn will be about 1350 gallons of fuel. Alot of fuel is burned on take-off.

Small planes use as little as 3 gph. Passenger jets use nearly 3000 gph @ takeoff power.

It depends on airplane type,size,loads and flight conditions.Big plane can consume one liter per second while small plane consumption does not exceed more than 0.1 liter per second ,it depends as I said.

A jet will burn anywhere from 150 to 1,000 gallons per flight hour. Here is a list of private jets and average hourly fuel burn: http://www.jets.com/private_jets.aspx

This is open to discussion and there are basically many possible answers to this question..

Well there is a question of weight,jet stream,and way too many veriables for anyone to answer that.
