One more note on checking in at KL Sentral (downtown train station) 8 hours before the flight. I was in the first class line and when I walked up to the counter the conversation was:

Me: "Hi, I'm on the 11 PM flight to Singapore and have an E-ticket."

Agent: "Passport please Mr. Yogi."

Me: (quickly checking for name tags) "How did you know who I was?"

Agent: "You are the only E-ticket. Checking one bag?"

Me: "Ah. Ok. Yes."
