I can confirm that an automated boarding announcement system should be in place by May. It is to be provided by the same suppliers of the system at Bristol and London-Luton airports, I believe the company is SimpleVox (correct me if I'm wrong). The software will also be able to make the announcements in the lanuage related to the destination (if it isn't English), except Welsh, unfortunately, as this will [apparently] require a £50,000 'add-on'...!
Hugely beneficial for the airport generally and a more professional image, and in-turn passengers!
