At this airport, count your lucky stars.

Let's give it a try.

Year after year, Singapore Changi Airport continues to win the best airport in the world award.

In fact, it's even marketed as it's own destination.

Sometimes families come here on weekends just to shop and dine.

In fact, I just met a couple of students who traveled here just to study and then go back home.

So how do you design the world's best airport? Let's find out.

It's not very common to find an airport that's carpeted, but here it's the norm.

Why? For one, it increases the luxury factor and number two, it helps absorb sounds,

so there's less noise, meaning passengers feel more relaxed.

Here in this terminal, the ceiling is using intelligent lighting

which controls the amount of natural light that enters the building.

After you're finished in the restroom, you're encouraged to

rate your experience based on the cleanliness of the toilets.

Now, this isn't done for Mr. Hassan's year-end review,

but it's actually collecting real-time data on how the restrooms are performing.

So for instance, if this one is getting a lot of 'Average',

operations staff know to send more people to here to figure out why.

So essentially now, the passengers are sort of, working for the airport.

This airport gets 1.8 million clicks of feedback like this per month. That's a lot of data.

There's multiple retail concept stores here at Changi. For example, this Whiskey House,

which has more than 100 different types of whiskeys available for complimentary tasting.

Many spirit brands decide to launch limited special edition products, specifically for this airport.

Why? Well, in addition to having high-end consumers pass through, there's also many nationalities.

In addition to plants being placed throughout the airport, there's five themed gardens like this one.

And 99% of all the greenery here, is completely real. And it's not exactly easy to maintain.

In addition to 10 plant specialists, there's more than 150 gardeners

working 24/7 to ensure its 'Excellent' standard.
