Transport in Indonesia
Air transport in Indonesia serves as a critical means of connecting the thousands of islands throughout the archipelago. Indonesia is the largest archipelagic country in the world, extending from east to west and from north to south, comprising 13,466 islands, with 922 of those permanently inhabited. With an estimated population of over 255 million people — making it the world's fourth-most-populous country — and also due to the growth of the middle-class, the boom of low-cost carriers in the recent decade, and overall economic growth, many domestic travellers shifted from land and sea transport to faster and more comfortable air travel. Indonesia is widely regarded as an emerging market for air travel in the region. Between 2009 and 2014, the number of Indonesian air passengers increased from 27,421,235 to 94,504,086, an increase of over threefold.

The administration of Indonesia is divided amongst 34 provinces, four of which are located in Melanesia (the others are located in Southeast Asia). The four Melanesian provinces are Maluku, North Maluku, Papua and West Papua. It is unclear whether any of these provinces has adopted an official flag.
