Online Reviews Summary
Singapore Changi Airport (SIN) consistently receives high praise from travelers, often hailed as one of the world's best airports. Recent reviews from 2024 and 2025 highlight exceptional satisfaction levels, attributing this to its seamless travel processes, extensive amenities, and commitment to passenger comfort and enjoyment. The airport's innovative design, blending functionality with lush greenery and immersive experiences, makes it a destination in itself.
What Travelers Love
- Overall Experience & Aesthetics: Changi is lauded for transforming the often-mundane airport experience into something enjoyable and unforgettable, with stunning art installations and lush indoor gardens, including the Jewel Changi Airport with its iconic Rain Vortex (world's tallest indoor waterfall). It's frequently described as a "must-see" destination.
- Seamless Check-in & Biometric Customs: Travelers praise the incredibly smooth and efficient check-in and security processes. The airport utilizes Smart Check-In Kiosks and Biometric Immigration Gates with facial recognition technology, significantly reducing wait times. Since May 2024, Singapore has allowed citizens from all countries to use automated immigration lanes without prior registration.
- World-Class Facilities & Amenities: Changi offers a vast array of amenities, including a butterfly garden, rooftop swimming pool, movie theaters, spa services, and diverse shopping options. It was recognized for the World's Best Airport Washrooms in 2025, emphasizing its high hygiene standards, which include regular cleaning and the use of autonomous cleaning robots. It was also ranked the world's second cleanest airport in 2025.
- Exceptional Dining: The airport is celebrated for its diverse and expansive dining options, from local Singaporean cuisine to international favorites, with many outlets, including hawker-style food, open 24 hours.
- Efficient Security: Security lines are generally swift and courteous, with advanced scanners in many terminals often eliminating the need to remove laptops or liquids. Security often takes place at the gate in most terminals (except T4), which contributes to efficiency in the main areas.
Common Complaints
- Security Process at Gate vs. Central: While generally efficient, the gate-side security in most terminals (T1, T2, T3) can be a surprise for those accustomed to central security checkpoints. Terminal 4 has a more traditional pre-departure security setup.
- Biometric System for Twins: There have been isolated issues reported with the biometric system where it struggles to differentiate between identical twins traveling together, leading to confusion for staff.
- Lack of Express Rail & Overnight Bus Services: Despite good public transport, some travelers find the ground transport options to the city lacking an express rail service, and bus services are limited, without express or overnight options, particularly for those arriving late or departing early. This often leaves taxis or ride-hailing services as the only practical choice, especially with heavy luggage or for destinations outside the east.
- Immigration Services Ranking: While overall immigration is smooth, Singapore's Changi Airport was surpassed by Hong Kong International Airport in 2025 for best immigration services.
Overall, Singapore Changi Airport continues to set a global benchmark for airport excellence, consistently earning top accolades for its passenger experience, innovative facilities, and operational efficiency. While its land transport connectivity could see some improvements for after-hours or express services, the airport remains a highly recommended travel hub and a destination in itself.
