Abstract: As air transport serves a time sensitive market, the surface access to airports should be efficient and the airport-linked requirements be persistently updated. In the Indian context, there is an absence of dedicated transportation services to airports except for the city of New Delhi, where it has taken the first step by integration of dedicated airport express line with existing transportation system. Consequently, there is a need to emphasize on linking of dedicated transportation services in other Indian cities as a sustainable solution. Mumbai being the fourth most populated city in the world too lacks a dedicated transportation service to the airport, which is the second busiest airport in India and amongst the renowned in the world (Department of Economic and Social Affairs (UN), 2009). Therefore, the main objective of the study is to assess the need for emerging seamless ground accessibility to Indian airports by explicating the case of Mumbai. An interview survey was conducted to understand the trip characteristics of air passengers, their expectations and perceptions for making the mode choice. The results and conclusions were used in estimating cost and time savings per person per hour for the city of Bangalore, so that the same practice can be used for other Indian cities too.
