It has greeted many of us when we arrive at Ireland's largest airport - but it will soon disappear.

The large flight information board in the departures area at Dublin Airport's Terminal 1 is being removed over the next four weeks to be replaced with 15 information screens.

DAA says the change is part of an overall programme to modernise the terminal, which is more than 40 years old.

As part of this programme, ticket desks have been removed in T1 to create more space in the departures area - and a new wooden fascia has been installed in departures.

The current road upgrade at the departures level of the terminal is also part of this programme.

The flight information board in T1 has been in place since 2005 and had become a symbol of the airport over the past 10 years.

"We'll be sorry to see the big board go, but the way in which passengers avail of information has changed dramatically over the past decade and we have to move with the times," said Dublin Airport spokeswoman Siobhan O’Donnell.

The flight information board, which was designed and constructed by the Spanish company Ikusi, is made from four separate panels and was originally installed in January 2005.

It is 11.3 metres long by 3.4 metres high and weighs 4.5 tonnes.

The work to remove it will be carried out at night during the airport’s least busy period, to minimise any impact on the travelling public.
