FLIGHTS IN and out of Dublin airport continued to experience delays yesterday, but air traffic control operations have generally returned to normal, the Irish Aviation Authority (IAA) said.
The radar system at the airport broke down last Wednesday, resulting in a reduction in the number of flights air traffic controllers could process.
Thousands of passengers experienced delays on inbound and outbound flights from the middle of last week and through the weekend. A spokeswoman for the IAA said everything was "going well" yesterday.
"We are operating at a level where there have been a few delays. But not all delays in flights are due to IAA factors."
A spokeswoman for Aer Lingus said the airline's departing flights yesterday were delayed by 25 minutes on average, while incoming flights were delayed by about 30 minutes.
The Dublin Airport Authority said operations yesterday were "pretty much back to normal".
The IAA is expecting a report on Wednesday from Thales ATM, the French company that manufactures the radar equipment in use at the airport.
Minister for Transport Noel Dempsey said last week he would seek a full report from the IAA.
Meanwhile, City of Derry Airport will be closed to scheduled and charter flights tomorrow and on Thursday due to industrial action by local government employees.
Members of the Unite union have rejected the offer of a 2.45 per cent pay increase and are seeking 6 per cent or 50 pence an hour, whichever is the greater.
Unite official Albert Mills said the union believed the pay deal was not in the interests of its members.
The lowest grade worker in local government is paid £5.81 (€7.28) per hour, just a few pence above the minimum wage, he said.
BA/Loganair services to Glasgow and Dublin have been cancelled on both days and the airline will contact passengers directly regarding rebooking.
Ryanair said its Derry services will also be cancelled and passengers would be accommodated on flights to or from Belfast.
The airport has set up a customer service line at 028 7130 5039.
