Most non-capital groups are set up to atract the non-flyers, these people think that they will fly but don,t but still keep up the paying the standing charge.
I know of at least one group that looses money each time the aircraft flys but has a majority of people who fly so infrequently that they are paying all the fixed costs and doing next to no flying.
All I can say is that try getting one of these aircraft on a bank holiday weekend in the summer.
If you can only fly at weekends you will find these are very expencive aircraft in the long run and you will be paying for the weekday pilots cheap flying.
