Is 86.9% A Good On-time Rate?

Wed Sep 07, 2005 6:08 am

My local airline Euromanx has published it's on-time rate for the week ending Sun 21st August. The figure is 86.9% of flights on-time, with 92.9% of flights arriving within 1 hour. Is this a good rate or not?

Euromanx have been plagued by problems recently, most of them resulting from a lack of pilots, caused by the airline trying to expand too quickly. This has meant they have had to charter a large number of aircraft so flights are rarely operated by the aircraft type published in timetables.

They also are a UK based airline operating under and Austrian AOC. Why can't they get a UK AOC?

86.9 is not bad, but with the problems... what is their completion factor??? I would keep an eye on fast expansion though... thats not always a good thing.

Quoting Gg190 (Thread starter):
86.9% of flights on-time

In itself this figure is excellent, however what do they call on time?

Is on time, precisely on time at the scheduled departure time published to the fare paying public? - I doubt it.

Is on time, scheduled departure time +5mins after (this was the case in the days that I worked with KLC) - More likely.

Is on time, scheduled departure time +15 mins after (as in the case of most LCC's I'm aware of) - The most likey.

Even so, there are so many variable which can affect an airline's OTP (On Time Performance), that having a +15 minute window is not unreasonable to be considered on time.

If this is the case, then these may or may not be contributing the the airline's own OTP statistics, as these flight will not actually be operated by the airline themselves. Therefore, it leads on that as these sectors are operated by another company, then Euromanx themselves will have less sectors to operate and will have a lot more "give" in the operating schedule enabling them to better absorb any delays that they themselves may be suffering.

Also, if an airline cancels a flight, these details will not be recorded as part of OTP stats because the flight did not actually operate and therefore it is irrelevant if it was on time or not because it simply didn't go as planned.
This fact can also aid the company's OTP.

It's a bit of a sneaky way to make the stats more pleasing to look at, but being in the industry for 11 years and for 3 different airlines, we all do it, so these statistics can (theoretically) be directly compared.

Quoting Gg190 (Thread starter):
92.9% of flights arriving within 1 hour

Arrival stats are always better as there will be a margin or window built into the published departure and arrival times to accommodate possible ATC delays, long taxy, awaiting push-back etc etc.

All said however,

Quoting Gg190 (Thread starter):
86.9%

, is still good.

The question about AOC's, I'll have to leave someone else, any takers......???

The comparison of the number of flights actually operated by the airline, against what they publish as their full schedule.

ie cancellations or possible sub-charters to another carrier.

AS far as I know all of euromanx's routes are operated under their own flight code (3W), so I assume they are operate by them. However they frequently use chatered aircraft and crew. Air Atlantique do a lot of work for them.
