Summaries
CO2 emissions from the jet fuel burned per passenger on an average 3200 kilometers (1992 miles) airline flight is about 353 kilograms (776 pounds). #ref1 Loss of natural habitat potential associated with the jet fuel burned per passenger on a 3200 kilometers (1992 miles) airline flight is estimated to be 250 square meters (2700 square feet). These estimates do not include the environmental impact of Radiative Forcing Index (RFI). #ref2

Emissions factors:
Short flights (less than 281 miles): 0.64 lbs of CO2/mile
Medium flights (281 to 994 miles): 0.45 lbs of CO2/mile
Long flights (over 994 miles): 0.39 lbs of CO2/mile

10,700 km (6,642 mile) British Airways flight by a 777 aircraft
Economy Class = 738.3 * 1.00 ratio = 738.3 pounds CO2 / seat
Prem. Econ. Class = 738.3 * 1.30 ratio = 959.8 pounds CO2 / seat
Business Class = 738.3 * 2.69 ratio = 1,986.0 pounds CO2 / seat
First Class = 738.3 * 3.02 ratio = 2,229.7 pounds CO2 / seat
If these pounds of CO2 / seat are multiplied by the number of actual seats in each cabin, the total will be 241,708 pounds CO2 for the flight, but now the emissions are properly allocated to seats in each cabin.

Radiative Forcing Index (RFI)
Convention has been to characterize the global warming potential of all species of emissions in terms of their CO2 equivalents. RFI is the ratio of the total amount of radiative forcing caused by all factors compared to the radiative forcing caused by CO2 emissions alone. The determination of this ratio is a focus of much current scientific study and debate. In 1992, the RFI for all aircraft emissions was estimated to be 2.7. This means that the combined effect of all aviation emissions, and their effects on atmospheric conditions, is 2.7 times the effect of CO2 alone. http://carbon.trx.com/TRX_CO2_Emissions_Documentation_v1.4.pdf
