ATR Identifies 209 New Indonesia Routes

Franco-Italian turboprop manufacturer ATR says it has identified 209 new domestic air routes across Indonesia that would be economically viable using regional turboprop aircraft, pointing to a market of roughly 16 million passengers a year that remains largely untapped despite existing airport infrastructure already being in place.

The headline figure behind the study is a striking one: of Indonesia's 180 paved-runway airports, 70 currently have no scheduled passenger service at all. That leaves substantial room for new domestic routes without the major infrastructure investment that usually gates network expansion in archipelagic markets. The runways, aprons and terminals already exist. What is missing, in ATR's framing, is an aircraft sized correctly for the demand.

Inside the data

The findings come from ATR's proprietary MobilityMonitor platform, which tracked the travel patterns of 35 million Indonesian residents — a sample the company says is representative of the broader population. That group made roughly 780 million inter-city journeys over the course of a year, using a mix of cars, motorbikes, buses, ferries, trains and aircraft.

Crucially for a turboprop manufacturer, around 90% of those journeys fell between 100 and 800 kilometres — a distance band ATR argues is well suited to turboprop economics, where the fuel-burn advantage over a regional jet is largest and where the sector length is too short for a jet to reach an efficient cruise profile. By cross-referencing the most common travel corridors against Indonesia's existing airport network and then scaling the sample data to estimate total market size, ATR arrived at its list of 209 candidate routes.

Why the geography matters

Indonesia is one of the few large aviation markets where the case for a 70-seat turboprop is structural rather than cyclical. The country spans more than 17,000 islands across three time zones, and a significant share of inter-city movement that would be a road or rail journey elsewhere has to cross water. Ferries absorb much of that demand today, at journey times measured in hours rather than minutes.

That is the gap ATR is aiming at. On thin, short, over-water sectors, a turboprop can operate frequencies that a narrowbody jet cannot fill, and it can work from shorter, less developed runways. The company's data suggests the outer islands stand to benefit most from any such expansion — precisely the regions where surface alternatives are slowest.

A study, not an order

It is worth being clear about what this is. ATR has published a market analysis, not announced a customer commitment. Turning 209 theoretical routes into flying schedules requires airlines willing to take on the aircraft, route economics that survive contact with real fares and load factors, and regulatory slot and licensing processes that the manufacturer does not control.

Manufacturer demand studies of this kind are, unavoidably, marketing documents as much as research: the conclusion that the market needs more of the product the company builds is not a surprising one. But the underlying infrastructure figure — 70 unserved paved-runway airports — is a concrete data point that does not depend on ATR's modelling assumptions, and it goes some way to explaining why the manufacturer keeps returning to Southeast Asia when it talks about growth.

Indonesia already operates one of the larger ATR fleets in the region, and the aircraft type has long been the default choice for domestic feeder networks across the archipelago. Whether the 209-route figure translates into aircraft orders will depend far more on Indonesian carriers' balance sheets over the next few years than on the strength of the market study itself.
