Indonesia's Busiest Airports in 2026: Soekarno-Hatta Leads as Q1 Traffic Hits 38.2 Million

4 min read

Indonesian air travel keeps climbing. In the first quarter of 2026, the 37 airports operated by InJourney Airports handled 38.20 million passengers — up roughly 5% from 36.38 million a year earlier — and Soekarno-Hatta International Airport (CGK) once again sat firmly at the top of the list.

The Q1 2026 numbers at a glance

  • 38.20 million passengers across 37 airports (January–March 2026), vs 36.38 million in Q1 2025.
  • 28.38 million domestic and 9.82 million international passengers.
  • 299,759 aircraft movements, up 8.7% from 275,782 flights a year earlier — flights grew even faster than passengers.

Two peak seasons fell inside the quarter and did most of the work: the tail end of the Christmas–New Year holidays in January, and the Ramadan and Eid al-Fitr travel wave in March. InJourney Airports CEO Mohammad R. Pahlevi credited “strong collaboration with airport stakeholders” for absorbing the peak-season demand without major disruption.

The top 5 busiest airports

# Airport City Q1 2026 passengers
1 Soekarno-Hatta (CGK) Tangerang / Jakarta 13.48 million
2 I Gusti Ngurah Rai (DPS) Denpasar, Bali 5.34 million
3 Juanda (SUB) Surabaya 3.21 million
4 Sultan Hasanuddin (UPG) Makassar 2.34 million
5 Kualanamu (KNO) Deli Serdang, Medan 1.80 million

The gap at the top is striking: CGK’s 13.48 million is more than the next three airports combined, and roughly 35% of all traffic across the 37-airport network. Bali’s Ngurah Rai holds a clear second place on the strength of international tourism, while Juanda, Sultan Hasanuddin, and Kualanamu round out the five.

What this means if you’re flying through CGK

A busier airport is mostly felt at the pressure points: check-in rows, security lanes, immigration, and the kerb. A few practical take-aways:

  • Peak seasons are the real story. The growth concentrates around New Year and Eid. If you fly in those windows, add 30–60 minutes to your usual buffer.
  • Watch the live board, not the printed schedule. More movements mean more gate changes and knock-on delays. Check the live departures and arrivals boards before you leave for the airport.
  • Plan ground transport ahead. Kerb-side queues grow with passenger numbers. The Airport Train and TransJakarta bypass road congestion entirely — see our full transport comparison for fares and pickup points.
  • Know your terminal. The busiest airport in the country is also one of the most spread out — check terminal facilities and the free Skytrain schedule before you land.
