We have around 350 fewer flights to and from Russia each day and we have some restricted airspace areas such as the eastern parts of Poland and Hungary. Long-haul flights between Europe and the Far East are having to fly considerably longer; most of the airliners are not equipped to overfly the Himalayas – because of the weight of the extra components – so they have to fly more southerly or westerly routes. This adds between one-and-a-half hours and four hours to the flight, depending on destination and origin.
Traffic flows that have shifted slightly west or south have been well absorbed without any significant increase in delays.
There is another possible impact we are analysing. The rise in oil prices and a consequent rise in ticket prices, which for the moment has been counter balanced by a continuing strong demand for travel.
