I can see there is a website for Indonesian train tickets but I am unable to find a comprehensive website for Indonesia bus services.
I am looking to buy tickets for the following itinerary:
- Jakarta to Bandung,
- Bandung to Wonosobo,
- Wonosobo to Jogjakarta,
- Jogjakarta to Malang,
- Malang to Ijen carter
Which is the cheapest option to buy tickets in Indonesia besides buying in advance?
