Where these numbers come from

Observed service A carrier record shows this named operator serving this named pair, and we carry that through unchanged.

Schedules, seat counts and fares are generated by our own model until the supplier contracts are signed. Places, coordinates, operators, which operator serves which pair, and every distance are real. We would rather say that on every page than let a modeled number pass for a filed one.
