Jetstar’s on time performance stats stretching the truth once again

By Steve Biddle, in , posted: 23-Sep-2014 10:00

I wrote a few weeks ago about Jetstar’s on time performance in New Zealand. Today they’ve taken out banner ads on many major NZ websites promoting they are “New Zealand’s most punctual airline”, and promising a $25 voucher if your flight is more than 10 mins late between the 23rd and 30th September.

The problem with Jetstar’s claims is that they facts don’t quite back up their bold claim of being “New Zealand’s most punctual domestic airline”.


Jetstar back up this claim with some fine print. They also admit that they are not comparing identical statistics as they’re reporting Air NZs entire domestic operations for half of the financial year, and only jet operations for the other half of the year.

*Best domestic airline on-time performance for July 2013-June 2014, at 10-minute departures. Source: ACARS for Jetstar statistics. Monthly reports to NZSX for Air New Zealand statistics. Air New Zealand reports included all aircraft types for July-December 2013 and jet aircraft only for January-June 2014.

It’s certainly worth noting that they’re talking about arrival times with their promise, but only publish scheduled departure statistics (and on NZ flights their scheduled flight times are 5 mins longer than Air NZ to allow a buffer for any delays).

Lets look at the published departure statistics for both airlines:


Looking at the statistics published on the Jetstar website for the July 2013 – June 2014 financial year, Jetstar have an average on time departure performance of within 10 minutes of 86.59%

Lets have a look at the results of Air New Zealand. A quick look at their publically listed statistics from the nzx website includes the following comment.

In the 2014 financial year, 86.5% of Air New Zealand’s Domestic Jet flights departed within 10 minutes of scheduled departure time.

Air NZ operate a much larger fleet and operate significantly more domestic flights across their NZ operations than Jetstar. Air NZ also had a terrible start to the year with major on time issues due to the introduction of their A320 aircraft which they have now recovered from. Despite this Air NZ have an 86.5% on time departure performance percentage across the Domestic Jet Fleet vs Jetstar on 86.59%. Looking at the bigger picture it poses the question – factoring all of this in, is .09% the big difference Jetstar would have you think it is?
