Ibesco was a tour operator run by a Michael Zwebner. I seem to remember he had headrest covers printed with
Charter Airlines but that is all. He never had an airline.
We also flew for Ibero, our own Island Sun Holidays, many many tour operators and even Dan Air subs when their 1-11's or 146 was not too reliable.
We also had schedules to Sicily and Malta.
