I built a better CGK Airport website

I just shipped jakartaairportcgk.com, a fast and easy-to-access website to browse all CGK airport info. Live arrival/departure schedule, skytrain (Kalayang) schedule, terminal facilities, and services list.

Why I built it

The official Injourney CGK website is bad. Like, really bad.

A few things that bug me:

1. I can’t open it from overseas. The site somehow blocks international requests. This is wild because international airports are supposed to be, you know, accessible internationally. Compare this to Changi Airport, which works fine from anywhere in the world.

2. The accessibility is terrible, both for humans and search engine crawlers. It takes multiple clicks just to go from Google search to actually seeing the arrival/departure list. They don’t even rank first when you search for it.

3. Performance is unreliable. The site times out a lot. “Took too long to respond” errors are common.

So I built my own.

Quick benchmark

I ran Lighthouse / PageSpeed Insights on three sites. Here’s what I got.

1. Changi Airport (departures page)

2. Injourney CGK Airport (flight schedule page)

I can’t even benchmark this one with pagespeed.web.dev because they block requests from it. So I had to use Lighthouse in Chrome DevTools on an Indonesian ISP.
