anyone has any idea how long a taxi ride would take from LCCT to downtown KL

It is between 45 mins to an hour but you could have just used google for that info. Fairly costly, there are a couple of bus companies from the LCCT with regular departues to Central for 1/10th of the price.

Agree, unless you wish to go to a specific address the bus is OK, but after arriving in KL Sentral its still time to get a taxi from there onwards.

KLIA 2 will be opening this year, it will be served by the KLIA Express train, which is great. Still end up at KL Sentral though.

I'll be glad to see the end of visits to the present LCCT Terminal, its like a warehouse (in fact I think it was build as a cargo terminal in the first place).

Plus

Sepang International Race Track is on the same road that leads to the present LCCT Terminal and the traffic is 100% horrendous when an event is on at the track. Went to watch the 2013 MotoGP round at Sepang, trying to get back from the track at about 7 pm on Sunday night took 3 hours to reach KLCC.

On successive visits to KL, I admit that I try to spend as little time in the heart of Bukit Bintang as humanly possible, but I have yet to see/hear a train arriving on the monorail. To my surprise, it's supposed to be no more than 12 minutes between trains to and fro KL Sentral at any given time of the day. I guess they must all be out at the evocatively titled Titiwangsa each time I stagger onto the square opposite the world's largest Maybank branch

so I guess when landing at around 10.25 am you can never get at the embassy downtown at 11.30am in time?

No chance mate, will take you about 30 minutes to get out of the airport alone.

Taxi will take about 45 minutes, depending on traffic.
