If BA ever tell you that your flight departing Dublin is "under airport control" and you should go to the ticket desk at the airport (as I was told by Laura from BAEC yesterday) ...

You need to inform them that there is NO ticket desk at DUB that handles British Airways flights ... and that they need to deal with ticketing!

The friendly staff member at the BA check in desk phoned up the London ticket office and the London staff member amended my ticket yesterday afternoon ... which was a bit of a waste of everybody's time - since I had phoned up BAEC an hour previously!!
