Since the first post about Indonesian airline punctuality and on-time performance was published in August 2011, many people still ask whether a certain flight will be on time.

It is hoped that this page meets this popular demand for the newest/most up-to-date statistics.

On-Time Performance

On-time performance is what percentage of flights leave within 15 minutes of the scheduled departure time. It is measured by when the plane leaves the departure gate.

The airlines are placed in alphabetical order (not by rank) so readers can find the rating of the airline they want more quickly.

The background shade is according to the airline’s current grade:

• 90-100% = white (excellent)
• 80-90% = green (good)
• 70-80% = yellow (ok)
• < 70% = red (unsatisfactory, needs improvement)

Airlines who consistently score below 70% face administrative sanctions from Indonesia’s Department of Civil Aviation. For example, they will not be permitted to increase flights or open new routes until their on-time performance has improved.

Airline	On-Time	Performance	(%)		Change
	Jan-Jun 2011	Jul-Dec 2011	Jan-Jun 2012	Jul-Dec 2012
	70.3	73.9	70.6	72.0	1.4
	86.2	82.5	85.5	85.0	0.5
	70.2	62.7	75.1	74.0	1.1
	76.1	63.8	66.3	69.8	3.5
	74.2	62.3	78.9	79.8	0.9

Cancellations

Cancellations are measured as scheduled flights which did not depart. It is not known whether cancelled flights count as a flight delay in the above table.

Each airline has a rank from 1 to 6, 1 being the airline with the lowest percentages of cancellations. Unlike flight delays, there appears to be no minimum standard/maximum percentage permitted for cancellations.

Airline	Rank	Cancellation Rate 2011 (%)
	#1	0.2
	#2	0.6
	#4	0.8
	#3	0.7
	#6	9.2
	#5	4.1

It is worth noting that sometimes airlines cancel a small number of flights for business reasons. For example, an airline which flies between Denpasar and Lombok 5 times a day might cancel the flight which has the smallest number of passengers and put the passengers on the previous/next flight the same day. This still counts as a cancellation, but provides minimal disruption to the passengers. Passengers in this circumstance may or may not qualify for the recently introduced financial compensation scheme.
