"Passenger destinations" pie chart

[NovemberCharlie]

Hi,

I was wondering how the passenger destinations pie chart works?
For example: in GW3 I fly out of HECA. Right now the chart tells me 27% is domestic.
There are 12 airports in Egypt I can fly to. So I can rule out that it shows how many airports have demand to HECA (as this would mean 100% is 44 airports, and I already fly to quite a few more airports).
The largest of these routes has has 150 pax per day and the longest is 464nm. Say this applies to all domestic routes this would give a total of 69600 ASKs.
Given that the longest route out of HECA (to KLAX) already gives 1912260 ASKs, I can also conclude that it is also not representative of ASKs.

So what does it show? In my eyes it is fairly useless at this time...

Well, to my understanding it would not be based on destination numbers, but on pax numbers divided by route type (Dom/Intl/LH).
However, some months ago Sami told me that it was mostly inaccurate.
So its only use is to know the average profile of the airport, and that's all.

Still that calculation would be pretty awful.
Sticking with my HECA example, being generous there are 1800 domestic passengers from CAI.
Given that the combined demand of LHR, AMS, CDG and FRA is already equal to the domestic demand should be minimal.

May I suggest removing this graph and simplifying it to just show that the airport has any or all of the three demand types?

I'd say yes and no.
Inaccurate, sure, but something still got to show the profile of the airport.
Otherwise, you'd have to scramble through the route planning to find out that JFK has a large LH share when in Atlanta it's comparatively minimal.

Sadly, I have no idea right now..
