LCCT (Low Cost Carrier Terminal) is serving Low Cost carriers like Air Asia, Tiger Airways etc. It is located some 20km from the Main Terminal Building of KLIA (MTB). There is shuttle bus from MTB to LCCT. Proceed to the bus station at the multi storey carpark / car rental building or just follow the sign. The fare is RM1.5 (not sure but very minimal). Or you can use taxi (proceed to taxi coupon counter)

Transportation to KL City, from MTB there's a fast train, or ERL fare RM35 (28min to city) if from LCCT there's plenty of buses to KL Sentral Station fare RM9

Hope this info will help
