Singapore Changi Airport receives approximately 65 million passengers annually across four terminals, making it the sixth busiest international airport globally by passenger traffic. Terminal 5 commenced construction in 2020 with an expected completion date of 2030, adding capacity for 50 million more passengers. Terminals 1, 2, and 3 interconnect airside through the Skytrain automated people mover, while Terminal 4 operates independently with separate immigration facilities. Jewel Changi Airport, opened April 2019, attaches to Terminal 1 and functions as a mixed-use facility featuring the 40-meter-tall Rain Vortex waterfall and five stories of retail and dining. The airport sits 17.2 kilometers from the central business district along Singapore's eastern coast in the planning area called Changi.
Immigration processing at Changi Airport uses automated gates for passport holders from 45 countries including the United States, United Kingdom, Australia, and all European Union member states. First-time visitors to Singapore from these countries use manual immigration counters, after which they gain automated gate access for subsequent visits. The Immigration and Checkpoints Authority captured biometric data for all arriving passengers beginning in January 2009, including fingerprints and facial photographs. Citizens of China, India, and Georgia require visas before arrival and cannot apply at the airport. Most Western passport holders receive 90-day entry permits automatically, while citizens of Russia and several Commonwealth nations receive 30 days. The official visa information appears only at https://www.ica.gov.sg/enter-transit-depart/entering-singapore.
Currency exchange counters in all four terminals operate 24 hours but offer exchange rates approximately 3 to 5 percent worse than rates available at licensed money changers in the city. Travelex and The Arcade money changers maintain counters in the arrival halls. ATMs from DBS, OCBC, UOB, HSBC, and Citibank appear before and after immigration in all terminals, dispensing Singapore dollars at the interbank rate plus individual bank foreign transaction fees. Singapore fully eliminated capital controls in 1978, and no restrictions exist on currency amounts carried in or out. The Singapore dollar trades freely at exchange rates that fluctuated between 1.25 and 1.45 per US dollar from 2020 through 2024.
SIM cards for tourists sell from Singtel, StarHub, and M1 counters in all arrival halls. A 100GB data plan valid for 30 days costs between 15 and 18 Singapore dollars depending on promotional periods. Singapore allocated 5G spectrum in 2020, and nationwide 5G coverage reached approximately 95 percent of the island by 2023 according to Infocomm Media Development Authority reports. The three carriers use physical SIM cards rather than eSIM for tourist plans, requiring passport presentation at purchase. Mobile data operates on IMDA OpenNets fiber infrastructure providing speeds that commonly exceed 300 Mbps in the central areas. Free WiFi networks called Wireless@SG appear throughout the terminals with no time limits, though connection requires registration with a mobile number capable of receiving SMS.
The Mass Rapid Transit East West Line green line connects Changi Airport to the city through Tanah Merah interchange station. Changi Airport MRT station opened January 2002 beneath Terminals 2 and 3, with covered walkways connecting to Terminal 1. The journey to City Hall station in the central business district takes 28 minutes and costs 2.50 Singapore dollars with an adult standard ticket. Trains begin service at 5:31 AM on weekdays and end at 11:18 PM. Terminal 4 connects to the MRT via a free shuttle bus operating every 12 minutes. EZ-Link stored value cards purchased from machines in the station cost 5 dollars deposit plus initial value but reduce per-ride costs by approximately 15 percent compared to standard tickets. These cards function across all MRT lines, public buses, and certain convenience stores.
Public bus service 36 operates from all terminals to Marina Bay and Orchard Road areas between 6 AM and midnight, taking approximately 80 minutes depending on traffic conditions. Bus 24 connects to Kampong Glam and Little India in roughly 60 minutes. The adult bus fare to central locations costs 2.20 dollars with an EZ-Link card or 2.50 dollars cash exact change, as drivers do not provide change. Public bus stops appear on the basement level of Terminals 1, 2, and 3. Singapore eliminated all public bus conductors in 1984, requiring exact fare payment or stored value cards. The SBS Transit and SMRT operators jointly serve Changi Airport under contracts from the Land Transport Authority.
Taxi queues at all terminals lead to metered Comfort, CityCab, SMRT, Trans-Cab, or Premier vehicles. The fare to central Singapore ranges from 20 to 30 dollars depending on destination, with mandatory airport surcharges adding 5 dollars during peak hours (5 PM to midnight on weekdays) or 3 dollars during non-peak hours. Midnight to 6 AM trips add 50 percent to the metered fare. Taxi meters begin at 3.90 dollars for the first kilometer and add approximately 0.24 dollars per subsequent 400 meters when traveling above 10 kilometers per hour. The journey to the Marina Bay area takes 18 to 25 minutes without traffic, extending to 35 to 50 minutes during morning rush hours from 7 AM to 9 AM or evening rush from 5 PM to 8 PM. All licensed taxis display registration numbers beginning with S and accept cash or card payment, though cards incur a processing fee of 10 percent of the metered fare.
Ride-hailing services Grab and Gojek operate from dedicated pickup points on Terminal 1 (Level 2), Terminal 2 (Level 1), Terminal 3 (Level 1), and Terminal 4 (departure hall). Grab established Southeast Asian headquarters in Singapore in 2014 after acquiring Uber's regional operations in March 2018. Fares to central areas range from 22 to 40 dollars depending on surge pricing multipliers, which commonly reach 1.5x during the morning arrival wave between 6 AM and 10 AM. Both applications require foreign credit cards or local bank cards for payment, as cash payment options ceased in Singapore in October 2019. Grab charges a 3 dollar airport pickup fee in addition to distance-based fares. The Competition and Consumer Commission of Singapore investigated Grab's market dominance in 2018, resulting in requirements to maintain separate driver pools from Gojek.
Private car services including Blacklane and local operators charge fixed rates from 55 to 90 dollars for sedans to city center hotels, with booking required at least two hours before arrival. These services meet passengers in the arrival hall holding name cards. The Land Transport Authority requires all private hire vehicles to display purple decals since January 2020, distinguishing them from taxis with yellow or red plates. Singapore maintains no legal category equivalent to airport shuttle vans, as the government eliminated shared ride services in 2013 following the transition to the distance-based fare system for public buses.
Baggage claim at Changi Airport typically begins within 20 minutes of aircraft parking. The airport guarantee commits to delivering the first bag within 12 minutes for flights on Singapore Airlines, Singapore's flag carrier founded in 1972. Lost baggage claims process through airline counters in the arrival halls, as Changi operates a decentralized system rather than a central lost and found. The Civil Aviation Authority of Singapore requires airlines to provide interim expense payments of 200 dollars within 24 hours for delayed baggage, though this represents airline policy rather than statutory requirement. Oversized baggage including surfboards and golf clubs emerge at separate collection points marked in each arrival hall.
Customs in Singapore employs red and green channel separation. The green channel requires no declaration for goods up to 500 Singapore dollars in value, excluding tobacco and alcohol which carry strict limits. Duty-free allowances permit zero cigarettes for travelers arriving from Malaysia, or 200 cigarettes from other countries. Alcohol allowance stands at one liter of spirits and one liter of wine or beer. Singapore imposes mandatory death penalty for drug trafficking amounts exceeding 15 grams of heroin or 500 grams of cannabis under the Misuse of Drugs Act, with airport searches including random baggage X-rays and detector dog deployment. Chewing gum import for personal consumption became legal in 2004 but remains restricted to therapeutic gum purchased from pharmacists. The Singapore Customs website at https://www.customs.gov.sg lists prohibited and controlled items.
