CNBC has explored how Changi Airport (Singapore) is designed, and points out three reasons for bringing the world's best airport to the airport for five years.

Changi Airport

Changi Airport recently announced plans to open the complex by 2019, with a 5-storey airport garden and several other attractions to maintain its leading position. Lions Island has been voted the world's best by Skytrax for five years, and is also considered by many bloggers to be the best airport to sleep in.

Changi Airport has many services and facilities: from free movie theater, outdoor swimming pool to butterfly garden with over 1,000 insects of 40 different species. The airport is even marketed as a separate destination for visitors to Singapore. It is not uncommon for families to go to Changi for shopping or dining. This is also a good place for students who want to find coffee shops to study. Here are three reasons why Changi is the best airport in the world, according to the US news agency.

1. Feedback from customers

Changi receives more than 1.8 million monthly replies from passengers. Feedback includes many aspects, from toilets, customer service areas to gardens. Partial data is actually used to inform Changi's current operation. For example, customers leaving the toilet can evaluate the facilities by selecting 5 excellent, good, average, temporary or very bad. The airport operator supervises the data, deploying staff clean up to any underserved receiving point.

2. Strange design

The story of a carpeted airport is quite rare, but not strange in Changi. This is a point to increase the level of luxury, but also a sound absorbing material that makes the airport noisy and chaotic. A quieter airport makes it easier for guests to relax.

3. Overflowing with nature

Changi prides itself on the number of trees, including the entire vegetation that passengers can encounter at the stations and in the five main gardens. This is not easy to maintain. The airport employs 10 outside professionals, full-time and 150 gardeners to work 24/7 to maintain the green.
