Just for kicks (and because I need to develop the skills anyway), I did a statistical analysis on the cancellation figures from 2006-2008, using the master file acquired from the BITRE site. The analysis was performed on the raw figures on a sector-by-sector basis (rather than the rolled numbers as the averages per month).
Comparing QF (only QF mainline, doesn't include QF-link) v DJ, QF did cancel more flights than DJ on average, but the difference in averages is not significant. If QF+JQ v DJ was compared, then the difference starts to become more significant, but even then it isn't very pronounced. In fact, with the QF+JQ v DJ 2006-2008 dataset, QF+JQ actually have a lower rate of cancellations compared to DJ.
One clear difference though is the variability in each of the data sets. The QF and QF+JQ data is more variable than that of the DJ data.
Having said that, of course the analysis is a bit rough (due to the analysis methodology and underlying assumptions), but it is a little better than just saying "since our average is 25% better than your average that is that". I haven't tried bringing in the other year's data sets, let alone factoring in QF-link into the QF set and Regional Express into DJ set.
It doesn't matter what kind of analysis is done or who is the "better" airline in these terms. Reading the master sheet there are notable examples of underperformance in terms of OTP (departures/arrivals) and cancellations from both airlines in at least the last 2-3 years. Both airlines have work to do and that is that. Coming to a conclusion that your rival needs to do more work than you or whatever is pointless; just run the airline and get on with it...and perhaps with a smile and a bit of class (no pun intended).
Interestingly enough,
JohnK, the lowest OTD (on-time dep) in 2007-2008 within the SYD/MEL/BNE network was 50.4% on SYD-MEL during July 2008, with a corresponding OTA (on-time arr) of 45.8%. The bottom ten records of OTD in the SYD/MEL/BNE during 2007-2008 are scooped up all (bar one) by QF; no surprises there! Having said that, though, the monthly OTD has never been less than 50% for any of DJ, QF or JQ during any year of 2003-2008 in the SYD/MEL/BNE triangle.
Is it acceptable? Of course not. So what can you do?
- Start your own airline
- Switch to the competition
- Stop flying planes (try another mode of transport)
- Nothing (just grin and bear it)
