The latest DfT aviation forecasting methodology and results were reported in 'UK Air Passenger Demand and CO2 Forecasts' (2007), available at:


The following table shows the forecasts for total and transfer passenger travel through Heathrow and Gatwick airports.

Forecast UK terminal passengers (million passengers per annum, mppa) and transfer shares of total
Transfer passengers mppa Transfer passengers (percentage)
Total passengers mppa Domestic to/from international International to international Domestic to/from international International to international
2010 74 6 23 7 31
2020 94 4 25 4 27
2030 136 4 36 3 27
2010 36 1 3 3 8
2020 38 1 3 2 8
2030 41 1 2 1 6

DfT forecasts of demand at each airport depend on capacity assumptions at all UK airports. These forecasts assume the central 'White Paper' case, including an extra runway and associated terminal capacity at both Stansted and Heathrow.
