There have been numerous instances where employers have favoured licences issued from certain national aviation authorities over others
Care to give specific, well documented examples of this, please? Not that it matters to me personally, mind you
the UK CAA took over 5 weeks to issue my A320 type rating.
Bah, I know of someone whose Metro type rating had already expired by the time he received it from a certain Iberian country's authority
I concur with the statement that the CAA is expensive but fairly efficient. OTOH I don't have experience with any other authorities so I'm not in a position to make comparisons.
