heading 125,
As a rule of thumb the smaller the aircraft then the more expensive, per seat, it is to operate thus, as an example, a B737-800 operator can offer cheaper fares than a B737-300/A319 operator who can offer cheaper fares than a B737-500 operator and so on but only if seat sales attain expected targets.
However, as has been demostrated, CWL does not have sufficient enough of a catchment area to fill LoCo B737-800's, indeed B737-500's, if one wishes to travel from CWL then one needs to appreciate that CWL has a lesser catchment area than, let us say, BRS who's catchment area spreads from mid point to BHX, mid point to LHR, mid point to SOU, and all the way down to Lands End.
If any person wants 'bucket shop' fares them move to a bucket shop
