I was done after a couple of hours when I decided to check Uber for nearby drivers. There was one 2 minutes away and I took it as a sign to leave, otherwise I wouldn't know when there would be another car: The guy just happened to be outside JPO and was about to call it a day when I made the request, so it was fortuitous for everyone involved.
I hadn't flown out of Senai before, so I was a bit confused at departure - it was just ONE guy at a podium, matching names on boarding passes and IDs of hundreds of people in line. And the one X-ray machine. Oy vey.
The on board meal was not bad, but because it was only an hour long flight, I had to wolf it down :P
