This is assuming you care about how thick your wallet is when you do get to the city. If your only concern is speed then your best bet would be to just get the RapidKL train that goes from KLIA to KL Sentral. I don’t think that train stops by the LCCT, but if you’re flying into the LCCT I doubt you’re going to want to ride that train anyway. The last time I checked I think the tickets were 35 RM per person, per trip.
So, if you’re looking for the best way to get to Kuala Lumpur without paying excessively high fees, just use the bus.
As you’re walking out of the LCCT terminal, just past customs, you’ll see some booths on the left with people selling tickets. If you go through the sliding glass doors and see the sign for the toilet, you’ve gone too far.
You can get a round trip ticket, good for one month, on the Aerobus for 14 RM. That’s a damn good deal and the ride isn’t bad at all. The train gets you to KL Sentral in about 20 minutes. The bus does it in 50 minutes for a fraction of the cost.
After you buy your tickets, exit through the sliding doors, walk forward until you see the McDonald’s, then make a right and follow the sidewalk down past the Mary Brown and the Coffee Bean (or Mr Bean? forget which). You’ll see buses pulled up along the sidewalk. You need to find berth number 4.
The buses you’re looking for will look like this:
There are similar buses going out of KLIA. It may be the same operator, but I don’t remember for sure. I’ve only flown into KLIA once, whereas I’ve gone through LCCT twice. I can’t remember exactly how to get to the buses but there are signs. The costs are nearly the same as well. I think the tickets are 9 RM apiece. I don’t know if there’s a deal for getting a round trip ticket. Regardless, it’s still cheaper than a train and definitely cheaper than a taxi.
Bus Service Quality
If you’re wondering about the bus quality, they’re in good shape. Depending on what countries you’ve been in you might be used to seeing beaten up buses. That’s not the case with the buses shuttling between KLCC / KLIA and KL Sentral.
The buses are clean. There’s no eating or drinking allowed onboard. The seats are pretty comfortable and they recline. It’s a luxury type bus with cushioned seats, rather than a city bus with hard plastic seats. So, you get to really relax. There’s no TV or radio in them but they are air conditioned.
The buses all drop you off on the lower level of KL Sentral. That’s good because most hotels / hostels / etc. are along the train or monorail routes and you can easily get to the train or monorail from the drop off point.
For the train, you just go up the stairs and into the building. You can’t miss it.
For the monorail you have to go around the block that’s adjacent to KL Sentral. Depending on how soon you go (relative to this post) you’ll notice that the area you have to go around is under construction. It’ll be to the right of the bus as it pulls in. Your best bet is to just follow the crowd. A lot of people will follow the sidewalk around to where the monorail is as they get off the bus.
Here’s a map to give you an idea:

The bus will drop you off on the road that’s just below the RapidKL marker on this map.
