Do I need to go through an agent to buy a plane ticket in Indonesia now?

No need. Indonesia * * * The Republic of China (hereinafter referred to as Indonesia) is a Southeast Asian country with Jakarta as its capital. Because the plane ticket is bought with your own ID card, it has nothing to do with the agent, and you don't need to go through the agent. A sales agent is an agent entrusted by a manufacturer to sell some specific products or all products of the manufacturer.
