Kuala Lumpur's new low-cost terminal is scheduled to start operations on 28 June after several rounds of delays.
"All efforts are being made towards this target date," says operator Malaysia Airports.
It adds that works that are near completion at KLIA2 include the paving of the runway and building of the air traffic control tower. Within the terminal, air-conditioning systems and check-in counters are being installed and tiling works are being carried out.
The shifting of operations from the current terminal to the new terminal is also being done in phases, says Malaysia Airports.
Last year, the airport operator offered 110 million new shares to fund the construction of the new budget terminal.
The new terminal will have the capacity to handle 45 million passengers annually.
The airport was originally due to open in March last year but this was delayed several times. Last year, the airport operator and AirAsia also went public with their spat over the delays and escalating cost of KLIA2.
