About Changi Airport Flight Performance

Changi Airport is one of the world's busiest airports, handling over 5,000 weekly flights across four terminals. On-time performance typically ranges between 75-85%, with delays most commonly caused by regional weather patterns, air traffic congestion in Southeast Asian airspace, and connecting flight delays.

Terminal 3 handles the highest volume of flights, primarily Singapore Airlines and Star Alliance carriers. Budget airlines like Scoot and Jetstar operate primarily from Terminal 1 and Terminal 4 respectively.
