To arrive to the international airport of Kuala Lumpur (75 KLIA) which is 10 kms. away from the centre we must calculate minimum one hour.
It actually took us one hour and 15 minutes, the taxi costs 70RM, fixed price. There is a train from the centre which connects with the airport and it costs 35RM.

We took a flight from Kuala Lumpur to Bangkok (1 hour and 15 minutes), and a second flight Bangkok-Munich (11 hours) and finally a flight Munich-Barcelona (1 hour and 40 minutes) with Lufthansa.
