Whilst it is fairly clear to anyone with a bit of sense that locos are indeed scheduled airlines, the distinction between the chartered and scheduled flights by the traditional charter airlines is a bit harder to define.
I'm off to Cyprus in October. Flying out of Glasgow with FCA. Bought the (e) ticket off the FCA website. Good price, no complaints. However, I could have purchased tickets on the same flight through a number of tour operators but they would have cost me something like £80 per skull more.
The flight, though, is advertised as a weekly scheduled flight and has a flight number of DP80. Normal FCA flights are prefixed FCA. So it appears that this airline sells seats on this flight to tour companies to sell on in much the same way as it would if it were a charter flight but retains a few to sell direct allowing it to call it a scheduled service.
Bet the seat pitch isn't any more...
