Data points on CGK transfers / I did AUH-CMB-CGK-KUL last time, this time I'm travelling in the opposite direction

I'm flying from KUL to CGK on Malaysia Airlines. I've checked in in advance and printed out my BP.

1. at KUL, the Malaysian agent told me that I can connect my luggage even on a separate booking, but I only did hand carry because I had to go back to SG in one day.

2. after landing at CGK, I showed my printed BP to the security agent near the transfer desk and explained the situation. He said he would call a staff member to help me,

3. an hour and a half later, an agent showed up to pick me up, and they escorted me through security.

I'm currently waiting in the lounge and my flight today is going to be delayed another 2 hours.. lol
