Economic environment influence airport service factorThe environment of airports service environment for the airline services, which will also influence travelling passengers' travelling destinations and travelling frequent times choices. The airport price factor includes income growth, aviation technology and local economic / geographical features of the country's domestic or overseas airports both. IN fact, airports, airports are indeed two sides businesses, it has commercial relationship between both airlines and passengers. So, airports' pricing will influence passengers' travelling demands to the airlines in the country. Any countries' airport(s) need(s) to respond how to help themselves country airlines how to increase passengers number and airlines choices in order to achieve attracting traffic on frequent air planes flying aim. Because the country's travelling passengers number increases , it will influence the country's airport(s) ' income increases indirectly, instead of the countries' any airlines themselves incomes.Hence, any country's airport(s) will be one good platform to let travelling passengers to stay in the country's airport(s). It means that id the country's airport(s) can build good service image and reasonable products sale price and comfortable shopping environment to attract any countries' passengers feel comfortable and worth to stay in themselves countries' airport(s), when they need to transfer air planes to stay in the country's airport, e.g. one hour to five hours short time, even overnight long time staying. However, if they feel the country's airport(s) are(is) more comfortable and clean to stay, less noise, as well as they have enough chairs to let them to sit or sleep and large area to let them to work in the airport ground floor.Moreover, the country's airport(s) can have enough restaurants , bookshops, any electronic or other kinds product shop[s, even cinema etc. shopping or entertainment services to satisfy the passengers whose eating needs, entertainment needs, shopping needs in the airport. Then, I believe that the country's airport(s) can help itself airlines to attract many passengersto choose to increase travelling times to the country frequently. For example, when the country's airport passengers feel that the airport restaurant food concessionaires will probably provide enjoy positive external gains from having more flights at the airports, additional or better eating facilities are unlikely to provide external benefits to the airlines by stimulating many more passengers with local origins or destinations to use the airport. I believe these airport restaurants can influence the choices of transit passengers whether which country will be their transfer air plane's short journey staying airport destination to fly to their final destinations. Although, transit passengers usually stay to the transfer air plane airport in short time, but they hope that these any one transit staying airport can have any restaurants to provide good taste food to them to eat when they feel hungry, if the transfer air plane country's airport can provide enough restaurants and they can have different food taste choice and reasonable price. Then, the airport's restaurants may attract many short time transit passengers to choose to eat their food, even many passengers will like to choose the country's airline to buy tickets to stay short time to wait to transfer another air plane to fly to their final destination to replace another country's airport to stay short time.
