What a load of ill informed garbage with a spurious title.
Registry of aircraft and its lease owners has SFA to do with how or where an airline operates.
Spanair operating from Barcelona had aircraft leased from Irish leasing companies, Sky Europe likewise, Malev and many other airlines across Europe had, have and will continue to have in the future.
A claim that somehow because the owners of the aircraft have registered their asset in a country before leasing to a company impacts on how the airline operates is laughable.
Where the airline is registered is where the AOC is applicable and has no bearing on the aircraft used.
GPA was one of the forerunners of Aircraft Leasing and following on from this an industry developed in Ireland specialising in this, helped by Irish Govt economic policy and low taxation.
I am not aware that because an aircraft is registered in one country it automatically prevents a 3rd country from inspecting or having anything to do with how the aircraft is operated. It has never been the case yet nor ever likely to be the case.
This thread belongs in the bin.
