The 15-minute window
is a pretty standard application of this type of this type of airline
performance metric. If you are looking
for a benchmark, Forbes
reported on a recent airline performance – the OAG 2019 Punctuality League
statistics – and they also use this 15 minute window. If you are looking for an international
benchmark, in the top 20 airlines for on-time performance for all airlines in the report, the top
airline was Copa Airlines with a 89.8 percent on time rate (that is arrived within
plus or minus 15 minutes of the scheduled arrival nearly 90 percent of the time). Rounding out the top 20 was Alitalia which
was on-time 82.9 percent of the time. If one only looked at mega airlines, the top 20
ranged from 85.6 percent for LATAM Airlines Group to 66.8 percent for – Air Canada
– just below Air China at number 19 with 68.8 percent. By the way, Westjet had a 76.3 percent on time rate. Porter did not appear to be included in the
report.
Without giving to much
away early for the rest of the post, Air Canada’s Toronto to Thunder Bay on time
performance during the August 25th to September 7th
period was pretty abysmal as it did not even meet its low overall on-time
performance. Over this time period, the
planes were late 57 percent of the time with an average late arrival of 29 minutes. You might think that 29 minutes is not so bad
– but the time differential ranged from a maximum of 201 minutes (that is 2
hours and 21 minutes late for AC 1512 on September 1st) to 11
minutes early for AC 1512 the next day.
The accompanying figure plots each flight during this period and at
least 8 flights (that is about 20 percent of flights) were at least 50 minutes
late. The only good news is that during
this period, there is a slight downward trend in minutes late but there is
still a lot of room for improvement.
Keep in mind, aside from the last flight of the day which even if a
couple of hours late is able to take off as the first flight the next morning
on time – all the late flights coming mean a late flight the other way. And, this poor performance is during a summer
period where there is relatively good weather.
One can only imagine what this winter is going to be like.
So, there you have it. Air Canada has work to do period but it would
be nice if it could bring up its Thunder Bay run performance to at least its
overall standard – which is not great by international standards.
