The busiest airport in the world’s fifth-largest airport group is being rebuilt piece by piece — with an open ambition of 94 million passengers.
Soekarno–Hatta (CGK) is the busiest airport in the InJourney Airports network: 13.48 million passengers in Q1 2026, ahead of Bali’s Ngurah Rai (5.34M), within a 37-airport system that handled 38.2 million passengers in the quarter (+5% y/y; international 9.82M). Together with Bali, CGK accounts for nearly 89% of Indonesia’s international air arrivals.
The rebuild is terminal by terminal. Terminal 1C reopened with capacity lifted from 3 to 10 million passengers a year; a dedicated low-cost Terminal 1F for international routes is slated for inauguration in early 2026; and Terminal 2F has been refitted as a Hajj and Umrah facility. State-owned operator InJourney and the ministry talk openly about growing the airport from its current ~56-million capacity toward 94 million.
Service quality is following capacity: CGK climbed to #25 in Skytrax’s World’s Top 100 Airports 2025, from #28 a year earlier — a quiet but real signal for a hub that competes with Singapore and Kuala Lumpur for transfer traffic.
Indonesia’s airports handled 8.23 million passengers on ~62,000 flights across the 2025 Christmas–New Year window, with CGK absorbing the largest share. The Eid al-Fitr homecoming added 17 extra routes in 2025 — a reminder that this airport’s rhythm is set as much by domestic mudik traffic as by international tourism.
For travellers, the practical notes: the airport rail link runs to the city’s rail spine (see Rail Hub), terminals are spread out (allow inter-terminal transfer time), and the new LCC terminal should progressively pull regional low-cost capacity away from the main piers.
Watch the transfer play. If CGK genuinely moves toward 94 million capacity, Jakarta stops being just an origin-destination airport and starts bidding for the Singapore–Kuala Lumpur transfer market — that is where the #25 Skytrax ranking matters. For the reader planning a trip: fly into CGK for Java and the east, into Bali for the islands, and treat the Whoosh connection at Halim as the fastest way to turn a Jakarta layover into a Bandung day.
