Singapore Changi Airport stands as a testament to what an airport can be—not merely a transit point but a destination in itself. Consistently ranked among the world’s best airports, Changi has redefined the airport experience with its innovative design, efficient operations, and commitment to passenger comfort. This exemplary aviation hub has become synonymous with Singapore’s reputation for excellence and forward-thinking approach to infrastructure development.
History: From Swampland to Global Aviation Hub
The story of Changi Airport begins in the 1970s when Singapore faced increasing pressure to expand its aviation capabilities. Paya Lebar Airport, which opened in 1955, was struggling to cope with rising passenger traffic. By 1975, passenger numbers had soared from 300,000 in 1955 to 4 million, making expansion crucial for Singapore’s growing role as a global business center.
After careful consideration, the Singaporean government decided to build a new airport at Changi, despite the significant engineering challenges. The site chosen was primarily swampland on the eastern edge of Singapore, far from residential areas to minimize noise pollution and with plenty of room for future expansion.
In June 1975, massive land reclamation works commenced, involving more than 52 million cubic meters of landfill and seafill. About 2 square kilometers of swampland were cleared and filled with 12 million cubic meters of earth from nearby hills, while another 40 million cubic meters of sand were used to fill the seabed. In total, 870 hectares were reclaimed, significantly expanding Singapore’s eastern coastline.
Construction of the actual airport facilities began in 1979, with the laying of the foundation stone of the Terminal 1 superstructure. After six years of intensive work, Singapore Changi Airport officially commenced operations on July 1, 1981. The first flight to arrive was Singapore Airlines SQ101 from Kuala Lumpur, touching down at 7:10 am with 140 passengers. Shortly after, SQ192 became the first departure, leaving for Penang at 8:00 am.
In its first year of operations, Changi Airport handled 12.1 million passengers, nearly 200,000 tonnes of air freight, and 63,100 aircraft movements—remarkable figures for a newly established airport. The new facility was an immediate success, with 250,000 visitors (equivalent to one-tenth of Singapore’s population at the time) touring the airport within two weeks of its opening.
Changi’s development continued steadily over the decades. Terminal 2 opened in 1991 to accommodate growing passenger numbers, along with the introduction of Skytrain services to connect the terminals. The addition of Terminal 3 in 2008 further expanded capacity, featuring an innovative “butterfly” roof design that bathes the building in natural sunlight. Terminal 4, which opened in 2017, brought the airport’s total capacity to approximately 80 million passengers annually.
One of the most significant recent additions to Changi is Jewel, which opened in 2019. This nature-themed entertainment and retail complex connects the airport’s terminals and has become an architectural icon with its spectacular Rain Vortex, the world’s tallest indoor waterfall.
