The KLIA Main Terminal Building (MTB) now also referred to as KLIA Main is located in between the two runways.
The floor area of the terminal covers 390,000 m² (4,200,000 sq ft) and the building consists of 39 square roof units, which enables future expansion of the building.
There are a total of 216 check-in counters, located in 6 different islands, identified by the letters A – M (excluding I).
Multi check-in services are available, designed for the use of all passengers arriving, departing or in transit.
Self check in facilities are available in this airport since 2007, and KLM was the first airline to use the Common-use self-service kiosks.

The contact pier is an extension of the main terminal building with gates marked with prefix A and B for domestic departures, G and H for international flights.
The gate allocation is based on operational requirements, although it has been observed that Malaysia Airlines has been operating most of its operations out from the contact pier.
