Review of Jetstar Asia Airways flight from Jakarta to Singapore in Economy

My long overdue holiday is finally here!
I have an overdue vacation to Singapore, which is happening this week. Here's the thing. 9 August is Singapore's National Day, and JetStar promised to have a Singlish announcement day for flights, but unfortunately, Jakarta-Singapore is not one of them.
Sad.
Anyway, I was almost didn't make it because my Dad was waking up late. I mean, seriously!? Luckily the ticket counter closes at 9, so I barely make it, and by the time I arrived at the gate, it's already boarding.
Thanks a lot, Dad! =__=;

This is what happened during boarding, and as you can see, there's still a lot of people.

And right 10 minutes before the departure, the plane detached from the terminal, and right on time, the plane takes off.
Here's the seat pitch. Fit for 15 cm of me.

And you can buy the SIM on the plane! Something I actually did, that costs me S$ 15 and free tea.

Anyway, Jetstar, please be considerate that I'm going to show you, that this needs to be cleaned frequently.

As I arrive, by the time I went to Immigration, they told me that since my Indonesian passport was made overseas, they have to let me in manually instead automatically. At least they are very helpful.
