HiSky (or CA HiSky SRL to be formal) is an airline based in Moldova that flies commercial scheduled passenger flights. It is part of the same group of companies as HiSky Europe, a Romanian airline.
When flying between Moldova and Israel, one often sees an aircraft registered to the Moldovan airline and on the Moldovan register operating the flight. When flying between Moldova and Stansted, one sees ONLY aircraft registered to the Romanian airline and on the Romanian register operating the flight.
How do they get away with this from the CAA ? Don't they have to at least make a reasonable attempt at following nationality rules ?
