Jakarta Airport [CGK]

The official ranking: on-time performance by airline, 2023

These figures come from Statistik Angkutan Udara 2023, the annual air transport statistics book of the ministry’s Directorate General of Civil Aviation (Ditjen Perhubungan Udara). They cover domestic scheduled flights only, for the full calendar year, and are taken from the OTP reports each airline submits to the ministry. The book lists airlines by their company names; the brand you book is shown first.

The ministry’s own summary: 73.99% of domestic scheduled flights were on time in 2023, “or around 26.01% experienced flight delays”, which it attributed to weather, flight operations and other factors. It named Pelita Air, Garuda Indonesia and Citilink as the top three.

Three things stand out. Only Pelita Air cleared 90%. Citilink jumped more than 16 points after a poor 2022. And three Lion Group airlines — Batik Air, Wings Air and Lion Air — all fell back, Lion Air by ten points; Super Air Jet dropped nine. Bear in mind that the two airlines at the bottom, Susi Air and TransNusa, fly far fewer services than the big carriers, so a handful of bad days moves their percentage a long way.

One data note. The chapter table in the same book also lists Xpress Air (PT Travel Express Aviation Service) at 71.02% — the identical figure to Super Air Jet — while the summary table omits it. We have left it out rather than guess which is right.

How the ministry defines “on time”

The statistics book describes on-time performance as the match between the scheduled departure time and the time the flight actually operated, and calls it a control tool for airline operations. Three points follow from that.

• It is reported by the airlines. The source line under the table is the airlines’ own OTP reports (Laporan Ketepatan Waktu Badan Usaha Angkutan Udara Niaga). The ministry compiles them; it does not time flights itself.
• The threshold is not stated. The published statistics do not say how many minutes late a flight can be and still count as on time. The common international standard, used by the analytics firm Cirium, is within 15 minutes of schedule.
• “Not on time” is not the same as “owed compensation”. Under Transport Minister Regulation PM 89 of 2015, an airline’s obligations to you begin at a 30-minute delay, and rise in steps from there. A flight 20 minutes late may count against an airline’s OTP without giving you any entitlement. Our delays and cancellations guide covers what you are owed.

What has been published since 2023

The ministry’s publications page lists statistics books for 2024 and 2025, but as of 4 October 2026 both can only be obtained by filing an access request, and we have found no outlet that has reported their per-airline OTP tables. What is public is a mix of national averages, award announcements and claims:

Two readings are fair. Pelita Air has, by the ministry’s own account, kept the top spot since 2023. And domestic punctuality as a whole was slightly worse in early 2025 than in early 2024: the Director General told parliament that the main causes were airline technical and operational issues, management and weather, “but weather is more dominant”. Lion Air Group’s president director, Daniel Putut Kuncoro Adi, told the same hearing that passengers connecting between airlines at Soekarno-Hatta — landing at Terminal 1A and leaving from Terminal 3, for example — also drag OTP down.

Beyond that, nobody outside the ministry can currently rank 2024 or 2025 performance airline by airline. The point was raised in August 2026 at the Constitutional Court, where a group of lawyers and students is challenging the delay provisions of the 2009 Aviation Law: Alvin Lie, chairman of the air passengers’ association APJAPI, asked that OTP be published regularly so travellers can judge airlines for themselves.

An independent check: Cirium

The UK aviation analytics firm Cirium ranks airlines each year on flights arriving within 15 minutes of their scheduled gate arrival, from its own flight-tracking data. In its review of 2023 — the same year as the ministry’s table — Garuda Indonesia placed sixth in Asia-Pacific with 78.67% across 61,525 flights, according to Katadata’s Databoks, citing the full report. Cirium’s own announcement lists only the top five.

That is nine points below the ministry’s 87.78% for Garuda in the same year. The two are not in conflict so much as measuring different things: Cirium counts arrivals on Garuda’s whole network, international flights included, from independent data; the ministry counts domestic flights from Garuda’s own report, against departure time. It is a useful reminder of how much the definition matters.

For 2025, no Indonesian airline appears in Cirium’s Asia-Pacific top ten, which Philippine Airlines led at 83.12%.

Why the official figures may not match your experience at CGK

If you have sat at a gate at Soekarno-Hatta watching the departure time slide, an airline’s 87% may sound generous. There are structural reasons the official number and your trip can differ.

• It is a national average. The figure blends every airport an airline serves, from quiet regional fields to CGK, the country’s busiest. A national 75% can hide a much lower rate on congested evening departures from Jakarta, or a higher one.
• It is self-reported. The airlines supply the data, and the published book does not explain how it is checked.
• It arrives late. As of October 2026 the newest openly published table describes 2023. Airlines change fleets, crews and schedules faster than that.
• It is a year in one number. Rainy-season afternoons, Lebaran peaks and the occasional volcanic-ash closure all disappear into one annual percentage.

That is why this site built its own airline punctuality tracker for CGK. It measures Soekarno-Hatta only, every day, from the airport operator’s own flight records rather than from airlines, using the 15-minute standard; the methodology page explains exactly how. Each main airline has its own page — Garuda, Lion Air, Batik Air, Citilink, Super Air Jet, Indonesia AirAsia, Pelita Air and TransNusa.

Its history runs back to 11 January 2026. We are not quoting any airline’s figure from it here, because the figures move from month to month; open the 90-day view for the steadiest comparison.

What this means when you book

• Big gaps are real; small ones are not. The difference between about one flight in ten running late and about one in three is something you will notice over a few trips. The difference between 87% and 86% is not.
• Protect connections, not just the first flight. If you are changing airlines at CGK on separate tickets, check which terminal each flight uses and leave generous time. The airline that delays you is not responsible for the onward flight you booked with someone else.
• Check on the day. Whatever the annual number, the departures and arrivals boards tell you what is happening to your flight now.

What is not known

The per-airline OTP figures for 2024 and 2025, and the figures behind Pelita Air’s 2025 and 2026 awards, have not been published openly. The ministry’s statistics do not state the minute threshold it uses for “on time” or how it audits airline reports. Nor do they break OTP down by airport, so there is no official CGK-only ranking. We will update this guide if the ministry publishes newer figures.
