Jakarta Airport [CGK]

What was announced

On Saturday 26 September 2026, PT Hutama Karya (Persero), the state-owned construction company, said it is building what it calls the Integrated Building at Soekarno-Hatta. The statement was attributed to Hamdani, Hutama Karya’s acting Executive Vice President and Corporate Secretary, and was carried the same day by detikFinance, IDX Channel, Warta Ekonomi, VOI, iNews and others.

The building sits between Terminal 1 and Terminal 2 on an 18,487 m² site, with about 60,000 m² of floor space split between a two-storey South Wing and a three-storey North Wing that includes a mezzanine. Hutama Karya describes it as a transfer hub linking seven modes: the Skytrain, the airport train, private cars, taxis, buses, shuttle buses and intercity travel services. It is to include parking, drop-off and pick-up zones, passenger waiting areas and retail space.

“The Integrated Building is targeted to begin operating in February 2027,” the company said. The rest of the statement was about construction: steel shipped from Surabaya, concrete sourced near the airport, 5D Building Information Modelling to calculate materials and catch clashes between components, and a façade of orange-terracotta glass-fibre concrete panels perforated in the Mega Mendung cloud motif of Cirebon batik.

Where the project actually stands

Every report we found traces back to the same Hutama Karya statement. That makes the core facts solid — the company building it described it on the record — but it also means there is only one voice. We could not find a statement from InJourney Airports, which runs Soekarno-Hatta, giving its own opening date, or confirming who will operate the building and which transport companies will move into it.

There is also a small wording split in the coverage. Most outlets reported February 2027 as the date the building begins operating; Warta Ekonomi and VOI headlined it as the date it is completed. Those are not the same thing at an airport, where a finished building usually needs weeks of trials, operator agreements and signage before passengers are sent into it.

The problem it is meant to solve

Anyone who has tried to get from an arriving flight to the right bus at CGK knows the issue. Soekarno-Hatta’s ground transport grew terminal by terminal, and it is scattered as a result:

• The airport train does not stop at any terminal. Its station is between Terminals 1 and 2, and you reach it on the Skytrain — one more change, with luggage, before the train itself.
• DAMRI buses and shuttle vans such as Cititrans stop at each terminal separately, and the right stop depends on which terminal you are in.
• TransJakarta’s airport routes stop at the airport office area, which means a walk or a shuttle from the terminals.
• Taxis, ride-hailing and private cars each use the kerb and parking at whichever terminal you land in, and the pick-up points differ between them.

The result is that the right answer to “how do I get to X?” at CGK usually starts with “which terminal are you in?” An intermodal hub is the standard fix: put every mode in one building, reached by the Skytrain from every terminal, so a passenger only needs to know one place. Whether this building achieves that depends on details not yet published — above all, whether the bus and shuttle operators actually move their stops into it.

Terminal 3 and the train station

Two questions every traveller will ask, and neither is answered in what has been published.

Does the airport train station move? Nothing in the coverage says so. The existing Soekarno-Hatta Airport Railway Station, with the Skytrain stop on its upper level, already stands between Terminals 1 and 2, and both the train and the Skytrain are listed as modes the new building connects. The obvious reading is that the hub is built to join the existing station rather than replace it. That is our inference; no site plan or operator statement confirms it.

How does Terminal 3 connect? Terminal 3, the Garuda Indonesia hub and home to most full-service international carriers, is not mentioned at all. Today it is linked to the other terminals and the station by the Skytrain, and since the Skytrain is one of the building’s seven modes, that is presumably how Terminal 3 passengers would get there. No walkway or new link has been announced.

Now versus after it opens

About that February 2027 date

Treat it as a target, not a promise. It was stated by the contractor, not the airport, and no construction start date or progress figure was given, so there is no way to judge from outside how realistic it is. Four months from announcement to operation is tight for a 60,000 m² building that has to be tied into a railway station, a people mover and airport roads.

Airport construction dates slip routinely, in Indonesia and everywhere else, and a hub like this one also depends on things outside the builder’s control: agreements with bus and shuttle operators, new traffic routing, and signage across three terminals. If you are travelling in February or March 2027, check before you go rather than assuming it is open. We will update this article when the airport says anything about opening.

What it means for your trip

• Before 2027: nothing. Change terminals and reach the train on the Kalayang Skytrain, and use the airport-to-city guide for buses, shuttles and taxis. No stops or pick-up points have moved.
• Allow for the Skytrain. It is free and runs about every 13 minutes, roughly 04:30–00:20 WIB. If you are catching the train or changing terminals, budget 15–20 minutes for the wait and the ride.
• Check your terminal first. Until a single hub exists, your terminal still decides where your bus, shuttle or driver meets you. The departures and arrivals boards show it for your flight.
• From February 2027: check, then trust. If the hub opens, operators may move their pick-up points into it. Confirm with your bus, shuttle or driver which location they use.

What is not known

• When construction started, and how far along it is.
• The contract value, and who commissioned the building.
• Whether InJourney Airports, which runs CGK, stands behind the February 2027 date.
• Which bus, shuttle, taxi and intercity operators will move into it, and whether terminal stops remain.
• Exactly how it joins the existing railway station and Skytrain stop.
• Any link for Terminal 3 beyond the existing Skytrain.
• What parking will cost there compared with the terminal car parks.
