While there are no reliable global statistics on the extra mileage, regional estimates amount to 6-8% over the US and 10% over Europe (Kettunen 2005). The extra mileage is mainly due to inefficiencies in the air traffic control systems, due to storm systems or other weather events as well as holding patterns (waiting loops) before landing (Kettunen 2005). The actual flight distance between two airports is often considerably longer than the shortest distance between two airports. Since there is no distinct limit for short-haul we interpolate for flight distances in between 15km to get a smooth transition. Since the type of aircraft and the passenger load factors depend on the flight distance, we differentiate between short-haul (2500km). In case of non-direct flights with stopover, the two stages are treated as individual flights.
