Thanks for the reply. I share your concerns about the discrepancy of what the MRZ shows,with the actual Name field(s), and whatever else is being held on other databases, including that of the airlines and the API system. To be frank, I wouldn't be surprised if the MRZ only listed one of the two names, but I have no way of corroborating that. I simply know no-one who has gone down that route, and I am unsure where/who to ask! Finding someone who has a passport listing two names would be a great start in ascertaining how the whole system works.

The Greek embassy in London (where I'm based) is notoriously unhelpful. They don't really want to be dealing with passports (they encourage citizens to go back to Greece to deal with renewals) and for the ones that they do actually deal with, they've put a notice on the website that even after several complaints, they will not be deviating from the legal requirement of using a transliteration, rather than a translation.
