Jakarta Soekarno-Hatta Airport (CGK) Terminal Map

The passenger terminal complex at Jakarta Soekarno-Hatta Airport consists at present of three main terminals - T1, T2 & T3.  T1  with Concourses 1A, 1B & 1C is a domestic terminal.  T2 with Concourses 2F, 2E & 2D, is an international terminal, and T3 is a smaller domestic terminal and the first terminal you see on arrival at the Airport.   Terminal 1 is on the south side of the drive loop, and opposite of it is terminal 2 on the north side. The three terminals are served by a free shuttle bus and  the Soetta Sky Train shuttle.

Upcoming Developments:
While T1 & T2 are currently built in a semi-circle with parking facilities in front of them and the circle road between them, T1 & T2 will be merged.
T2 & T3 are being expanded (particularly T3) and are to be linked by a corridor, which includes a shopping area.
All expansion work is to be completed by late 2014.
A new Terminal 4 will be built in the future, as well as Runway 3. 
An automated transportation system will link terminals, shopping mall and hotel.

This is a most recent post by a traveler:   " ...Terminal 2....Entering the Check-In desks are modernized with automatic glass doors. Repainted white interior of the arrival gates, showing a more lively area. Here is the nice one, all alphabetical gates are accessible. Before, they were restricted, which was difficult for connecting passengers and transit...toilets are still as bad as the carousel area..."

NOTE: While Ankara Pura II (the airport Operator) now has an English-language airport site for its airports  - it has no airport map, no news regarding airport development, and  otherwise shows mostly passenger unrelated contents.
