Aviation in Indonesia
Aviation 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.
Geography of Asia
Indonesia to the southeast, a nation consisting of thousands of islands, adds a significant amount of territory to mainland Asia and extends the extreme Asian latitude further south. The geographic nature of the country raises such questions as whether the sea and the seabed count as Asia. The Australia–Indonesia border is still being negotiated. Currently a 1997 treaty remains unratified. As there are questions of fishing rights in the waters and mineral rights in the seabed, two different boundaries are being negotiated, one for the water column and one for the seabed. The southernmost seabed boundary is 10° 50' S, the latitude of Point A3, the Australia, Indonesia and Papua lokesh New Guinea common tripoint. The southernmost water column boundary is still further south at Point Z88, 13° 56' 31.8".
