Airline Ratings said the awards showcase airports that excel in making travel memorable and prove that the journey can be just as rewarding as the destination.
Many readers also praised Changi Airport for deserving with the honor.
"Traveling around the world, the absolute best airport is Singapore Changi. Every category from customer service to facilities, convenience, security, and efficiency is unmatched," a reader wrote.
"I was very impressed with Changi Airport. It's extremely customer-friendly and easy to navigate between terminals. My only regret was not allowing myself more time to explore," another wrote.
2024 marks a successful year of Changi as it has continuously been honored by international media.
Last year, it surpassed more than 60 rivals to the crown of world's best airport in a survey conducted by British newspaper The Telegraph.
Spanning more than one million square meters across four terminals, equivalent to 156 football fields, Changi Airport is celebrated for its state-of-the-art amenities, including duty-free shopping, luxury accommodation and automated check-ins.
