Eventually as an operator if you carry passengers for hire or reward whether "RPT" or "Charter" you will be treated the same by the regulator. This is hardly news. Under the present regs, doing joy flights just don't do it to a schedule, have aircraft and pilots available when you have enough pax to make it economical you take off. You only have to remove one of the conditions that make it RPT for it to be ad-hoc charter. That is until the regs change.
