British Airways estimates the current passenger traffic between India and London to be about 750,000 passengers per year, of which 375,000 is O&D, and the rest goes on to North America and Europe.
The current India-England bilaterals allow for 22,000 seats per week, each side, starting in summer of 2006- that is about 1.15 million seats per annum for each side. That is a total of about 2.3 million seats, far more than the current demand of 750,000 seats. With time, more of the North American market will be served with non stop flights from India, which in turn will reduce the demand on the India-London sector. It does not seem likely that the capacity of 2.3 million will ever be utilized. What is needed is open skies policy during winter and summer months to meet the highly concentrated demand.
Are British Airways number correct on the demand side? I welcome comments/corrections.
