8 out of 22 B747s plying that route have been reconfigured, whereas the other 14 remain in the old configuration, so it's your best guess whether you'll get the old or the new cabins. If you leave on one of the nights when the full passenger version 744 is deployed on KL809 AMS KUL CGK you have a good chance of getting the new cabins as 4 out of 5 aircraft have been reconfigured.
