Has anyone else ever managed to get their exams recognised by another state?
The Finns recognise UK ATPL exams, as do the Greeks, I believe.
However, you are the first person I know of who has got his foreign exams recognised in the UK, so congratulations on that point
btw, the language of your communications with the DGAC might well have been the only thing holding it back. Not so much because of their inability to speak English as for legal reasons, Spain having the concept of official languages. Just guessing though.
Having said that, it would be great if the Spaniards decided to start reciprocating by accepting British ATPLs.
