They have now changed the ams-kno route to ams-cgk.
Passengers holding bookings for kno have not been offered a connection to kno from cgk. Since this was the only European flight from kno, there was a small but significant knock-on as you could fly to AMS from pretty much anywhere in Europe direct, and get the non-stop to KNO. Now flying via AMS, from say Berlin to Medan, makes no sense
Usual Garuda mismanagement....
