I've always been a bit baffled why people remove cancelled flights when calculating load factors - surely what is relevant is tickets sold, not bums on seats. i.e at one extreme I could schedule a daily flight, see that sales are only at 50%, cancel every other flight and re-book pax on to the following days flight and claim 100% load factors? And yes, the obvious caveat that LF's doesn't tell us if a route is making money.
On a seperate note, are the CAA June CSV files incorrectly formatted or is it just me?
