take 858 and drop at Terminal 3. ( journey around 30-40
minutes during off-peak hour ) , take train which is
1 stop away.
Peak hour, forget about taking bus because it will jam like
siao.
yeah if you decide to take bus to airport, alight at terminal 3,
its nearer to train station
don't take the bus till terminal 2 because time will be wasted
on security checking the bus before entering each terminal
