Presumably where such figures fall down is where flights aren't "connecting". For example, if I was to travel Ryanair to Dublin from Bristol, then Aer Lingus Dublin to (random place) Frankfurt, that wouldn't show up because the two airlines don't have an agreement ("interline"?).
Sometimes you can extrapolate figures. For example, for BRS to EWR, CO had no real existing data to work on as no airline flies that route. So based on the number of people from the west country (the BRS catchment area) who travel via Heathrow to New York, you can estimate that perhaps 10% of those would switch to a local flight from a local airport.
So in reality, all you're going to get is a ballpark figure which could vary by 50% or more. Perhaps more accurate if that route is served directly or indirectly by other airlines.

Some centuries ago, when hell was frozen I made a summer internship at MEA (Middle east Airlines AirLiban). One of my (many) questions is how to assess the potential of a line. The manager of route development told me that there were many indicators :
1- Number of visas delivered between the 2 countries.
2-Expatriate population living in the 2 countries
3-Foreign investments made by either of 2 countries (business travel , cargo)
4-Passengers connecting at intermediate airport to .
All these information are made available through info from embassies and consulates and do not forget that in Africa, Gulf and Middle East passengers are still requested to fill in a disembark card with all appropriate information ( country of residence for ex, purpose of travel etc...)
