Changi Airport is Singapore's main public international airport. Located at the eastern tip of Singapore, it serves millions of passengers every month. Changi Airport has three conventional terminals Terminals 1, 2, and 3, plus one Budget Terminal which is a standalone no-frills terminal built to serve low-cost carriers. The Budget Terminal will be rebuilt starting end-2012 and operations are expected to cease in the second half of 2012, with flights operating out of it relocated to Terminal 2.
While well-known as an international air transit point, Changi Airport has also built up an extensive shopping and retail business spread throughout the premises of its terminals. Shops and eateries operating in public access areas and beyond the counters serve both local Singaporeans as well as tourists arriving, departing or just having a stopover at the airport. The airport has virtually transformed into a major retail mall in its own right.
Changi Airport has its own MRT subway station (CG2) which is the terminal station for the Changi Airport extension branch of the East-West Line.
By public bus:
Several public buses operate from other parts of Singapore to Changi Airport. The buses make stops at the terminals' basements and along Airport Boulevard.
Many taxis serve the airport with each terminal having its own taxi stands.
Carparks are available throughout the airport.
