Built at approximately RM4 billion, it is the largest purpose built terminal optimised for low-cost carriers in response to the exponential growth of low-cost travel in the region.
It was built to replace the previous Low Cost Carrier Terminal (LCCT).
klia2 started its operations on 2 May 2014 and all flight operations at LCCT were moved to klia2 by 9 May 2014.

As part of its development, a third runway (Runway 15/33) and a new air traffic control tower (Tower West) were built to support its operation.
klia2 has an initial capacity of 45 million passengers per year.
The terminal has a built-up area of 257,845 sqm with 68 departure gates, 10 remote stands, 80 aerobridges, includes a retail space of 35,000 sqm to accommodate a total of 220 retail outlets.
The main terminal building of klia2 is connected with its satellite piers with a skybridge, making it the first airport in Asia with such facility.
klia2 is certified with Leadership in Energy & Environmental Design (LEED).

Check-in counters are divided into 8 rows located in 4 islands, each row identified by the letters S – Z. Boarding gates are located in 5 piers, indicated by the letters J and K for domestic flights, and L, P and Q for international flights.
Piers J, K and L are connected directly to the main terminal building, while Piers P and Q are accessible via the skybridge.
Piers K and L are physically the same pier and share the same gates, but with waiting lounges on different levels (Level 1A for K and Level 2 for L).
For international flights, the access door from Pier K is sealed off, while for domestic flights, the access door from Pier L is sealed off instead.

At present, inter-terminal connection is provided on the landside at Gateway@klia2 complex and there are provisions for future airside inter-terminal connection.
