Singapore Changi Airport is the busiest airport in Asia, serving hundreds of international flights a day. The airport provides multiple transit options into the city, all accessible directly from the majority of terminals at Changi and all at reasonable prices, operating for all hours of the day and night. Changi airport taxis are available 24/7 and will take you in to the city in approximately 23 minutes for around €15 (S$25) - note that this price is affected by a variety of factors. Alternatively, there are two methods of public transport, by metro (MRT) or bus. The MRT will take you into the city for €1.20 (S$2), or €1.08 (S$1.75) with an EZ-Link card and take around 30 minutes. A bus, being the slowest option, will take around 1.5hrs and cost around €1.50 (S$2.50) or €1.18 (S$1.84) with an EZ-Link card. Welcome Pickups offers meet and greet services and a friendly introduction to Singapore at the same price as a regular taxi. Click here to see the cost.
