Sounds kinda nonsense even if it was just 10%... What happens to the rest of the PAX? They all move out to NA? They return in a boat? I don't think so. If you have a better explanation please tell me. Thanks for your help.
It can be a minimum of a 10% difference because your demand charts are, at best (depending on staffing level and morale level of your personnel), only 90-95% accurate. This is actually noted right on the charts themselves. They are not actual figures but rather estimates provided by your staff on what demand could potentially
be at default pricing.
So, let's say the demand on a route is actually 1000 pax at default pricing.
You open one chart going one way and it reads 'low' at 920 pax.
You check the return route and it reads 'high' at 1080 pax.
You have a net difference of over 15%. You can keep refreshing the charts and see just how much the demand changes; keep refreshing and you flip it around so the first shows much higher than the second. On particularly dense routes your personnel might be off as much as 1-2 flights per day in their best estimates of demand.
