Changi Airport, Singapore.
Speed, free cinema or a record-breaking waterfall. Changi is “a miniature Singapore” — a half-century investment that continues to bear fruit.
Imagine you have just landed after an 18-hour flight. Yawning and with red eyes, he prepares to face the usual difficulties of airports: the walk to immigration control, the queues that don’t move forward and the “infinite” wait for the luggage to be delivered.
However, instead, you find smiling, autonomous cleaning robots, managed by AI, cleaning the place’s immaculate floors. And immigration control moves so quickly that you spend a few moments suspecting that there is something there. In less than 15 minutes, you’re on the streetamid the tropical heat, wondering why, in the rest of the world, all this remains so difficult.
A few days later, you return to the airport, check in flawlessly for your return trip, and wait for your flight in the airport’s transit areas. Find one free cinema open 24/7, a butterfly garden and the world’s tallest indoor waterfall. You can even walk through a glass fish farming tank, with a screen on the ceiling that digitally mimics the weather outside.
Sometimes you forget that you are in an airport and feel like you are in a tiny, brilliantly managed futuristic city.
It may seem like a frequent flyer’s dream, but this place exists. And the Changi airportin Singapore, winner of the Skytrax award for the best airport in the world for the second year in a row — and for the 14th time since the award’s creation.
While other major airports face rodent infestations, strikes and collapsing ceilings, Changi’s futuristic peace feels like it belongs in another world. The distance between an average airport and a world-class airport has never seemed so great. But what does it take for modern air travel to run so smoothly? And how does Singapore manage to reach this level, while its competitors face so many difficulties?
Speed, security, connectivity, flexibility
Max Hirsh is general director of the Airport City Academy research center, dedicated to airport planning and development. For him, Changi’s success is not limited to quality.
The airport also ensures day-to-day essentials, such as speed, security and connectivity, as well as the flexibility to adapt when something does not go as planned.
“In the world of aviation, this happens a lot,” explains Hirsh. “The challenge is not to achieve balance in a single moment, but to maintain the standard over decades, in the face of changes in demand, technology and disruption. Changi succeeds because it treats this balance as an ongoing project, not as a one-off feat of design.”
First, efficiency; then the show
If you’ve ever flown to Singapore, you’ve probably noticed the sense of calm that permeates the airport. What probably goes unnoticed is how carefully this tranquility is produced.
Behind the scenes, there is a huge and tightly choreographed operation. Here, automation, biometrics and predictive analytics are used to eliminate bottlenecks before they become visible.
They are 60 thousand employees that keep baggage, cleanliness, energy consumption and passenger flow in perfect sync. In Hirsh’s words, Changi always seems to be “one step ahead.”
The same logic extends to less glamorous details. Backend infrastructure, such as intuitive guidance, clear signage and crowd managementcauses passengers, already affected by the jet lagdon’t waste cognitive capacity trying to find the boarding gate.
There is 500 bathrooms spread across the terminals, which also helps a lot. Each has a touchscreen for passengers to evaluate the experience. And any drop in ratings means a cleaning crew shows up within minutes.
“The hierarchy is simple,” explains Hirsh: “First, efficiency; second, environment; third, spectacle.”
The power of flow
Changi has so much to offer that it may take several visits to appreciate its full scope. The best-known example is the cascata interior Jewel Rain Vortexin the commercial complex attached to the airport. It has become one of Singapore’s best-known tourist images.
Travelers can also see Toni the robotic bartender from Changi, preparing various cocktails in terminals 2 and 3 of the airport.
O butterfly garden It imports chrysalises every two or three weeks, never to fail to display its winged wonders. And, if flying insects aren’t your thing, there’s also a cactus garden and a sunflower garden on the terrace.
The new zone Fit and Funopened in early 2025, is full of activities for all tastes. It offers everything from punching bags to mini-trampolines.
And, for those who have a longer layover — and don’t need an entry visa — the airport even offers free guided tours of the city.
Attractions are continually updated and do more than ease the burden of a long trip. They also have a more practical purpose: to encourage people to explore the facilities by walking to different areas of the terminal, and to help avoid the overcrowded feeling typical of other airports.
Ease of arrival and departure
Part of Changi’s efficiency comes from both pragmatism and ambition. Singapore’s labor restrictions have led the airport to adopt the automation in immigration and cleaning services, as well as other passenger services.
“Immigration services are labor intensive and not all Singaporeans are willing to do this work,” explains Ivan Tan, vice-president of corporate communications and marketing at Changi Airport Group. “So, in part, we are driven by necessity.”
In 2024, Changi became the first airport to fully implement passport-free immigration, using biometric facial and iris recognition to reduce time on what can be one of the most irritating parts of any international trip.
Singapore residents can use the system upon arrival and departure. International travelers can use control without a passport when leaving the country.
This mindset also helps explain why Changi Airport has actually never allowed itself to sit still. Airports are miniature cities, driven by rigid schedules and complex logistics. They are very vulnerable to volatility.
This is one of the reasons that led Changi to recently create the Terminal Xan innovation lab whose mission is to address weather volatility, labor issues, capacity limits and ever-increasing customer expectations.
“For us, the innovation center is indispensable,” says Kris Mok, the laboratory’s communications manager. He highlights that, due to the constant evolution of challenges, “in some years we will have to work twice as hard”.
Staff are encouraged to test strange ideas, even if they fail — an unusual approach in Singapore’s often cautious work culture.
Among the laboratory’s projects is a drone rub who fly during storms to prevent electrical discharges that could close the airport runways, in one of the most lightning-prone countries in the world.
“Singapore in miniature”
Changi’s obsession with efficiency is long-standing. It dates back to the 1970s, when Singapore’s founding father and first Prime Minister, Lee Kuan Yew (1923-2015), realized that for the small trade-dependent nation to grow, it would need a welcoming symbol that demonstrated efficiency.
The bet was expensive, but it paid off. Lee would later call Changi “Singapore’s best $1.5 billion investment [cerca de 3,2 mil milhões de euros, ao câmbio actual] that we have ever done.”
50 years have passed and the investment continues to pay dividends. “[Changi] It’s Singapore in miniature: efficient, clean, organized, and we can trust that everything works as expected,” says Alisha Rodrigo, a Singapore resident who frequently travels from the airport.
I speak to her shortly after a US government shutdown left US airports with four-hour wait times at immigration and check-in.
“Sometimes, predictability is a good thing”, highlights Rodrigo. And ultimately, this is why Changi keeps winning awards.
Visitors can take the memory of the waterfall with them, but the real achievement is that they managed to reach it without getting lost or even slowing down.
