Soekarno–Hatta International Airport (CGK) July 2025 Operational Report

Flight Activity Overview

Total Departing Flights: 14,916

Year-over-Year Change in Departing Flights: −1.24%

In July 2025, CGK handled 14,916 departures, a slight year-over-year dip as airlines refined schedules and capacity. Despite the marginal decline, Jakarta’s main gateway continued to anchor Indonesia’s network with robust regional links across Southeast Asia. The pattern points to stable demand with fine-tuning rather than structural weakness.

On-Time Performance and Cancellations

Departure On-Time Performance: 55.14%

Year-over-Year Change in OTP: −4.90%

Cancelled Flights: 248

Year-over-Year Change in Cancellations: −78.71%

OTP softened compared with last year, reflecting peak-hour congestion and turnaround pressure. The standout improvement was cancellations, which fell sharply year over year, giving travelers fewer severe disruptions and steadier schedules. For day-of-travel planning, this means more certainty even if minor delays remain.

Airlines Serving CGK

Key operators include Garuda Indonesia (GA) and Lion Air (JT), alongside a wide mix of regional and long‑haul carriers. The blend of full‑service and low‑cost options offers flexibility on price and departure times for both domestic hops and international trips.

Outlook

Heading into August’s dry-season period, weather-related disruptions are typically limited, which should support operational stability. With OTP softer but cancellations much lower year over year, passengers can improve their odds by choosing morning departures, monitoring gate changes, and allowing extra time during weekend peaks.
