*** Subang to LCCT damn fast can reach wanna ask so much.

If you can spend then take cab straight to LCCT.

If not, go to KL Sentral then take train to LCCT.

Sentral to LCCT within 1 hour.

Subang to Sentral also 1 hour give and take.

1:20 flight = check-in 11:20.

Arrive at SZB 8:20 after checkout, luggage claim should be 9:00.

2 hours = 11:00.

Elementary math also need help.

And as many have mentioned: IF you're really concerned about time, just take a cab directly to LCCT.

Won't take more than 2-3 hours.
