ON airport visit costs aspect, airlines also need to consider airport visit costs in their route development strategy. Visit costs may also influence passenger choice behavior when airlines pass on higher/lower charges to the passenger through air fares. Although, airport visit costs generally represent a limited share of an airline's total operational costs, this share can be more significant for short haul flights as well as fair airlines. All of any one these airport charges and passenger fees variable may influence passengers airlines choice. They may include: Fees variable, landing charge, parking charge for their vehicles or aircraft, passenger luggage charge, security charge, boarding bridge charge, noise charge, emission charge, airport development service increasing charge, check -in charge, terminal charge, cargo charge. So, if any one of these charges influence the airline ticket price rises, it will influence passengers' air ticket purchase choice to the airline in possible.On airport service levels aspect, for keeping and attracting passengers, airlines and airports need to compete with services that improve the passengers experience. Such servicefactors concern for immigration and luggage, but also relate to the terminals, waiting transfer another air plane time, shopping facilities, toilets, atmosphere and space cleaniness, friendliness of staff and availability of delicated lounges. Together they determine the image of an airport and its perceived value by passengers and airlines.On airline routes development aspect, it can also influence passengers choices to the airline, e.g. Australia airline had developed long route to England destination. Any Australia passengers can fly to England route directly. They do not need to transfer another air plane to go to England. Although, flying time is above 12 hours long time, but it can bring available to passengers. They do not need to spend time to wait another air plane to transfer to go England in Australia any airports. THus, airline route development strategy airline planners require detailed, accurate information to make new route decisions, but airlines usually do not have the resources to fully evaluate every new route market. So, they need a sound well articulated business case, can convince airlines to introduce new air services, as well as airport / destinations can influence the airline planning process.For example, Interviewer indicates that new routes are a huge investment and risk to an airline in airline economic view point, if the airline had not gathered any data to evaluate whether the new route is worth to develop and predict passengers' new route choice behavior. It assumed 75% lead factor will influence any new route development in success. It indicates these different aircraft type and seats per flight, annual passenger requirements data for these aircrafts: Boeing 747 aircraft needs to satisfy 400 at least seats per flight and annual passenger requirement need 219, 000, aircraft airbus A340 aircraft needs 280 at least seats per flight and annual passenger requirements need 153,300, Boesing 767 to 300 aircraft needs 220 at least seats per flight and annual passenger requirements need 120, 450 . Boeing 737 to 700 aircraft needs 76,650 and regional Jet aircraft needs 100 at least seats per flight and annual passenger requirements need 54,750.
