An end to the personal element of this incident, but opening up a whole new set of questions, Aer Lingus have issued a written apology confirming that there was no issue with the passenger or with the passports, and revoking the policy "for customers holding Greek passports" - presumably it stays in place for other customers.

Dear Dr. Ntislis
Thank you for taking the time to speak to me over the last few days.
From the outset, I offer renewed apologies for the upset and inconveniences caused to you on 6 January prior to your flight with us from Barcelona.
The test you were asked to complete was inappropriate and I assure you that our Handling Agents have been instructed that the policy to conduct a language test for customers holding Greek passports has been revoked. I am happy to confirm that their was no issue with you personally or with your passport.
As a tangible gesture of goodwill to a valued customer, I would like to offer a complimentary return flight on any Aer Lingus operated scheduled services on our European network to you, your husband and daughter. When you wish to avail of this, let me know the flights and dates required and I will personally make the necessary arrangements for you.
I look forward to hearing from you and I hope Aer Lingus will have an opportunity to serve you and your family again in the not too distant future.
Yours sincerely
James Clarke

There are plenty of new questions about why an Irish airline, flying Irish residents directly to Ireland, should conduct immigration tests on behalf of a foreign government, using tests supplied by the United Kingdom Border Agency. It is a big change from last week, when few people believed that the incident had occurred.
