According to wikipedia, a direct flight in the aviation industry is any flight between two points by an airline with no change in flight numbers, which may include a stop over at an intermediate point. The stop over may either be to get new passengers (or allow some to disembark) or a mere technical stop over (i.e. for refuelling purposes only). These are often confused with non-stop flights, which are direct flights involving no intermediate stops. When there is a change in flight number, the subsequent flight is referred to as a connecting flight. (See http:/wiki/Direct_flight.) And the sector "Airlines and destinations" in each of the airport article should be direct flights, not non-stop flights. That is to say, as long as the flight number or the aircraft does not change, a destination should be included in the sector. Therefore, it is not appropriate to delete destinations which include stop overs but retain their flight number or aircraft. Thank you.
