Flying Irishman
The registration of the aircraft in not relevant in determining whether Ryanair is an Irish airline. The test under both EC legislation and the Chicago Convention is where an airline has it principal place of business. There is no accepted definition of principal place of business so far as I am aware. However I agree that the location of the company HQ and flt ops, together with significant services out of Ireland make it hard to argue that its principal place of business is not Ireland.
