For international carriers flying from India, the Delhi-Tokyo (Japan) route offers the highest yield per seat for every kilometre travelled. War-torn Afghanistan might make many people think twice about visiting that country, but the Delhi-Kabul route is the second most profitable route. The yield per seat-kilometre between Delhi and Tokyo, at Indian Rs 14.54, is over three times the yields on Delhi to Singapore, London or New York. Similarly, the yield on Delhi to Kabul, at under Rs 9, is far attractive than other popular routes.
Airport planners say that with competition for traditional routes so intense, many carriers are now looking at routes which are under-served but where one can generate good margins.
